Abstract
An input device includes a touch panel incorporating a switch electrode region, and an actuator. The switch electrode region includes a switch electrode and a ground electrode disposed side by side with the switch electrode. The actuator includes a push button having an operation surface, an elastic body, a conductor, and a facing surface. The conductor faces the switch electrode region and is separated from the switch and ground electrodes. The conductor moves in line with a press put on the push button such that a capacitance value between the conductor and each of the switch and ground electrodes changes in response to a distance between the conductor and the switch electrode.
