An input apparatus includes: a touch sensor 11; a piezoelectric element 13; a piezoelectric element drive unit 15; a control unit 17 configured to detect a pressure load on the touch sensor 11 based on an output signal of the piezoelectric element 13 and, when the pressure load satisfies a standard to provide a tactile sensation, to control the piezoelectric element drive unit 15 to drive the piezoelectric element 13 such that the tactile sensation is provided to a pressing object; a connection switchover unit 14 configured to selectively connect the piezoelectric element 13 to the control unit 17 or the piezoelectric element drive unit 15; and a discharge circuit 16 configured to discharge electric charge in the piezoelectric element 13. When the pressure load satisfies the standard, the control unit 17 controls the connection switchover unit 14 to connect the piezoelectric element 13 to the piezoelectric element drive unit 15 such that the piezoelectric element 13 is driven, and then controls the discharge circuit 16 to discharge the electric charge in the piezoelectric element 13. |
