Input device

An input device comprising an insulation substrate, a switch element provided on the substrate, and a detection portion that detects a capacitance change at the switch element, wherein:

• the switch element comprises 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;
• and
• the fixed electrode portion is electrically insulated with respect to the movable electrode portion and is connected to ground.
