<p>In the present invention, a capacitance-type switch is provided with an operation plate (10) and an electrode plate (20). The operation plate (10) forms operation surfaces (11a, 11b) operated by the touch of a fingertip F (operation body) of a user. The electrode plate (20) is disposed on the side of the operation plate (10) opposite the operation surfaces (11a, 11b). Furthermore, the capacitance-type switch is turned on and off in response to the change in capacitance caused between the fingertip F and the electrode plate (20). In addition, a high-permittivity material (22) is disposed in an outer circumferential section (20a) of the electrode plate (20), the high-permittivity material (22) having a higher permittivity than the operation plate (10). It is possible to improve the sensitivity of the capacitance-type switch while minimizing malfunctioning.</p> |
