Abstract

An electronic device having a small size and improved in sensing ability is provided. A mobile phone 1 includes a first housing 2 having a housing opening 2h; a connector 67 arranged inside the first housing 2; a reinforcing frame 31 arranged to face the housing opening 2h to cover the connector 67; a sensor board 39 arranged on a surface facing the housing opening 2h of the reinforcing frame 31; and a touch sensor electronic 47 arranged on a surface facing the housing opening 2h of the sensor board 39. The reinforcing frame 31 has a recess 31d in a region which corresponds to the touch sensor electrode 47 and the connector 67.

Claims

1. An electronic device comprising:

a case member having an opening;

an electronic component arranged inside the case member;

a frame member arranged to face the opening to cover the electronic component;

a first circuit board arranged on a surface facing the opening of the frame member; and

an electrode for an electrostatic capacity type touch sensor provided on a surface facing the opening of the first circuit board,

wherein the frame member has a recess in a region corresponding to at least one of the electrode and the electronic component.

2. An electronic device as set forth in claim 1, wherein

the frame member is formed by a resin, and

a solid member having a smaller dielectric constant than that of the frame member is arranged in the recess.

3. An electronic device as set forth in claim 2, wherein

the recess is formed in the surface on the side where the first circuit board is arranged of the frame member, and

the solid member is arranged so that its surface becomes the same plane as the surface of the frame member.

4. An electronic device as set forth in claim 1, further comprising:

a switch member arranged on the surface facing the opening of the first circuit board and

an operating member arranged to be exposed from the opening and arranged to face the switch member and the electrode, wherein

the recess is arranged in a region which does not correspond to the switch member of the frame member.

5. An electronic device as set forth in claim 1, wherein

the frame member has a plate portion which is arranged separated from the electronic component to the opening side, and

the recess is formed in the plate portion.

6. An electronic device as set forth in claim 5, wherein the recess is formed at a position corresponding to the electrode on a surface on the side facing the opening of the plate portion.

7. An electronic device as set forth in claim 5, wherein the recess is formed at a position corresponding to the electronic component on a surface on the side facing the electronic component of the plate portion.

8. An electronic device as set forth in claim 1, comprising:

the device has a second circuit board which is arranged inside the case member and has the electronic component arranged at a position facing the opening, wherein

the frame member is arranged on a surface on the side facing the opening of the second circuit board.
