Abstract
An input device includes an insulation substrate, a switch element, and a detection portion. The switch element includes a fixed electrode portion that is provided on the substrate, and a movable electrode portion that is provided on a main surface side of the substrate, at least part of the movable electrode portion being elastically displaceable toward a direction approaching and leaving the fixed electrode portion. The movable electrode portion is displaceable toward a direction approaching the fixed electrode portion due to pressure from an object to be detected that is an electric conductor. The detection portion is capable of detecting a capacitance change caused by the object to be detected approaching and leaving the movable electrode portion and a capacitance change between the movable electrode portion and the fixed electrode portion produced by displacement of the movable electrode portion due to pressing.
