입력 장치는, 조작자에 의해 입력 조작이 행해지는 조작부와, 조작부에 대한 입력 조작을 검출하는 검출부와, 조작부에 대하여 진동을 부여하는 액추에이터와, 검출부에 의한 검출 결과에 따라, 액추에이터에 대하여 구동 신호를 공급하는 제어부를 구비하고, 제어부는, 구동 신호로서, 삼각파 또는 정현파로 이루어지고, 또한, 피크 위치를 경계로 하여 상승 구간과 하강 구간이 비대칭인 신호 파형을 가지는 단일의 펄스 신호를, 액추에이터로 공급한다. An input apparatus includes an operating unit on which an input operation is performed by an operator, a detecting unit configured to detect the input operation performed on the operating unit, an actuator configured to impart vibration to the operating unit, and a control unit configured to supply a drive signal to the actuator according to a result of detection performed by the detecting unit. The control unit supplies, as the drive signal, a single pulse signal including a triangular wave or a sine wave and having a signal waveform in which a rising interval and a falling interval are asymmetric about a peak position to the actuator.
