Damaging a touch sensor is prevented by an input apparatus including a pressing load detection unit 102 for detecting a pressing load applied by a pressing object pressing a touch sensor, a contact area detection unit 103 for detecting a contact area of the object on the sensor, a memory unit 105 for storing a pressing load threshold for receiving an input and a damage threshold higher than the pressing load threshold and varies according to the contact area, a control unit 104 for obtaining the pressing load threshold and the damage threshold corresponding to the contact area from the memory unit, and receiving the input when the pressing load reaches the pressing load threshold, or generating a warning signal when the pressing load reaches the damage threshold, and a notification unit 106 for receiving the warning signal from the control unit and outputting a warning.
