Abstract
A switch device includes: a first touch sensor portion to which one end of a first wiring portion is connected; a second touch sensor portion to which one end of a second wiring portion is connected; and a touch wiring portion having one end of which is connected only to the second wiring portion and the other end of which is open; the touch wiring portion being arranged such that when one capacitance is produced between the touch surface and the first wiring portion by a touch operation, the other capacitance is produced between the touch surface and the touch wiring portion by the touch operation; and the touch operation is disabled when detecting the one capacitance and the other capacitance. A finger touches a portion other than a touch sensor portion (wiring portion), and the touch is disabled, and thereby, a high reliability is achieved.
