Abstract: An input device includes: an input member that includes a first surface on which an operation is performed by an operation body and a second surface that is a back surface of the first surface; a first electrode that is disposed on the second surface; a second electrode that faces the first electrode and is disposed spaced apart from the first electrode; and a controller that detects a pressing force applied to the input member by an operation performed by the operation body, based on the electrostatic capacitance between the first electrode and the second electrode, and calculates a pressure-sensitivity value that is a value indicating the pressing force detected. Here, the first electrode is electrically connected to the ground.
