PROBLEM TO BE SOLVED: To provide a highly reliable switch device in which a switch does not perform wrong operation when a fingertip touches a part other than the switch.SOLUTION: A switch device (1) includes a first touch sensor part (15a) to which one end of a first wiring part (17a) is connected, and a second touch sensor part (19a) to which one end of a second wiring part (21a) is connected. In the switch device (1), a touch wiring part (31a) having one end connected only to the second wiring part and the other end open is configured so that: when a touch operation generates one capacitance between a touch object and the first wiring part, the touch operation generates another capacitance between the touch object and the touch wiring part; and when the one capacitance and the other capacitance are detected, the touch operation is disabled. When a fingertip touches a part (wiring part) other than the touch sensor part, the touch is disabled, thereby obtaining high reliability. |
