Abstract
An electronic device includes an input plane member that includes a plurality of first conductive layers that is elastically deformed when a pressing operation is received from a user, a base that includes a plurality of second conductive layers that comes in contact with the first conductive layer when the input plane member is deformed, a capacitance detection unit that detects capacitance between the plurality of first conductive layers and between the plurality of second conductive layers, a resistance value detection unit that detects a resistance value between the first conductive layer and the second conductive layer when the first conductive layer comes in contact with the second conductive layer, and a switch unit that controls electrical connection between the first conductive layer and the second conductive layer and either of the capacitance detection unit and the resistance value detection unit.
