Abstract

A channel device includes a first substrate having a groove portion for forming a channel, and a second substrate having a protruding portion that covers the groove portion, the first substrate and the second substrate being bonded together with an adhesive. The protruding portion of the second substrate extends along the extending direction of the groove portion of the first substrate, and mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are in direct and linear contact with each other without an adhesive therebetween, and the channel is thereby formed.

Claims

1. A channel device comprising:

a first substrate having a groove portion for forming a channel; and

a second substrate having a protruding portion that covers the groove portion, the first substrate and the second substrate being bonded together with an adhesive,

wherein the protruding portion of the second substrate extends along a direction corresponding to an extending direction of the groove portion of the first substrate, and

wherein mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are in direct and linear contact with each other without an adhesive therebetween, and the channel is thereby formed.

2. The channel device according to claim 1, wherein both opposite side wall portions of the protruding portion of the second substrate are in direct and linear contact with both opposite side wall portions of the groove portion, respectively, of the first substrate without adhesive therebetween, and the channel is thereby formed.

3. The channel device according to claim 1, wherein the adhesive is disposed outside the channel and bonds the second substrate and the first substrate.

4. The channel device according to claim 1, wherein the channel device is configured as a microchannel device.

5. The channel device according to claim 1, wherein the channel device has a fitting structure that, in a cross-section of the channel, a height of the channel from a bottom of the groove portion of the first substrate to a top of the protruding portion of the second substrate is constant in an extending direction of the channel.

6. The channel device according to claim 1, wherein the first substrate and the second substrate both have a flat plate shape.

7. The channel device according to claim 1, wherein a combination of a cross-sectional shape of the groove portion of the first substrate and a cross-sectional shape of the protruding portion of the second substrate is a combination of a rectangular shape and a trapezoidal shape, a combination of a rectangular shape and a circular shape, or a combination of two circular shapes having different curvatures.

8. The channel device according to claim 1, wherein materials for the first substrate and the second substrate are both selected from glass, plastic, metal, and inorganic compound.

9. A method for manufacturing a channel device including a first substrate having a groove portion for forming a channel and a second substrate having a protruding portion extending along a direction corresponding to an extending direction of the groove portion, the first substrate and the second substrate being bonded together with an adhesive, the method comprising the steps of:

applying adhesive to a predetermined part of at least one of the first substrate and the second substrate;

bonding the first substrate and the second substrate such that the groove portion of the first substrate and the protruding portion of the second substrate are aligned with each other; and

applying pressure to at least one of the first substrate and the second substrate after the bonding so that mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are brought into direct and linear contact with each other without adhesive therebetween.

10. The method for manufacturing a channel device according to claim 9, wherein both opposite side wall portions of the protruding portion of the second substrate are brought into direct and linear contact with both opposite side wall portions of the groove portion of the first substrate, respectively, without adhesive therebetween, and the channel is thereby formed.

11. The method for manufacturing a channel device according to claim 9, wherein the adhesive is applied to a part outside the groove portion of the first substrate and along the groove portion.

12. The method for manufacturing a channel device according to claim 9, wherein when applying the adhesive to the substrate, the adhesive is applied at a distance from a position where, after the bonding, mutually corresponding parts of the protruding portion of the second substrate and the groove portion of the first substrate are in linear and direct contact with each other without adhesive therebetween, and along the groove portion and/or the protruding portion, and when the substrates are bonded together, the adhesive fills up to a position where the first substrate and the second substrate are in direct contact with each other.

13. The method for manufacturing a channel device according to claim 9, wherein the first substrate, the groove portion, the second portion, and the protruding portion have sizes suitable for forming a microchannel device.
