Abstract: An input device includes a driver that supplies drive signals to a plurality of capacitive elements, respectively; a charge detector that detects a change in an electric charge corresponding to the drive signal in each of the plurality of capacitive elements; a capacitive element identifier that identifies the capacitive element to which an object approaches based on a detection result by the charge detector; an electric field generator that generates an electric field for reducing another electric field generated as an electric charge changes in the capacitive element when the driver supplies the drive signal to the capacitive element; and a controller that adjusts the electric field generated by the electric field generator depending on whether the capacitive element to which the driver supplies the drive signal includes the capacitive element identified by the capacitive element identifier.
