Abstract
An input apparatus includes: a touch sensor; a piezoelectric element; a piezoelectric element drive unit; a control unitconfigured to detect a pressure load on the touch sensorbased on an output signal of the piezoelectric elementand, when the pressure load satisfies a standard to provide a tactile sensation, to control the piezoelectric element drive unitto drive the piezoelectric elementsuch that the tactile sensation is provided to a pressing object; a connection switchover unitconfigured to selectively connect the piezoelectric elementto the control unitor the piezoelectric element drive unit; and a discharge circuitconfigured to discharge electric charge in the piezoelectric element. When the pressure load satisfies the standard, the control unitcontrols the connection switchover unitto connect the piezoelectric elementto the piezoelectric element drive unitsuch that the piezoelectric elementis driven, and then controls the discharge circuitto discharge the electric charge in the piezoelectric element
