Abstract

An electronic unit according to the present invention, the first support member has a first base body, and a first contact member extending from the first base body and making contact with the first main surface of the substrate. The second support member includes a second base body, and a second contact member extending from the second base body and making contact with the second main surface of the substrate. At least part of the area on the first main surface that corresponds to the region at which the second contact member is in contact with the substrate overlaps with the region at which the first contact member is in contact with the substrate. This electronic unit is capable of suppressing distortion in the substrate even when an impact is applied from the exterior. The electrical connection between the electronic component and the substrate can therefore be prevented from being disrupted.

Claims

1. An electronic unit comprising:

a substrate including a first main surface and a second main surface opposite to the first main surface, on which an electronic component is mounted, and

a support member that supports the substrate,

wherein the support member includes a first support member and a second support member, with the substrate being sandwiched between the support members;

the first support member includes a first base body, and a first contact member capable of being in contact with the first main surface;

the second support member includes a second base body, and a second contact member capable of being in contact with the second main surface; and

at least part of the area on the substrate at which the first contact member is in contact with the substrate overlaps with a region at which the second contact member is in contact with the substrate.

2. The electronic unit according to claim 1, wherein either the first contact member and the first base body are formed as a single body.

3. The electronic unit according to claim 1, wherein either the second contact member and the second base body are formed as a single body.

4. The electronic unit according to claim 1, wherein the first contact member and the second contact member are capable of being in contact with the substrate at the region that experiences the largest amount of distortion.

5. The electronic unit according to claim 1, wherein the center line of the first contact member and the center line of the second contact member are matched, and the center lines are center on the surface of the contact members that is in contact with the substrate.

6. The electronic unit according to claim 1, wherein the first contact member and the second contact member are capable of being in contact with the substrate in the vicinity of the electronic component.

7. An electronic apparatus comprising:

a housing,

an electronic unit that includes a substrate and a support member, the substrate having a first main surface on which an electronic component is mounted and a second main surface opposite to the first main surface, the support member that supports the substrate, the electronic unit being contained in the housing,

wherein the support member includes a first support member and a second support member, with the substrate being sandwiched between the support members;

the first support member includes a first base body, and a first contact member capable of being in contact with the first main surface;

the second support member includes a second base body, and a second contact member capable of being in contact with the second main surface; and

at least part of the area on the substrate at which the first contact member is in contact with the substrate overlaps with a region at which the second contact member is in contact with the substrate.
