1. A force-applying input device comprising:

  • an operating unit;

    a position sensor which detects an operational state of the operating unit and outputs a position signal;

    an actuator which applies an external force to the operating unit; and

    a controller which outputs an actuator drive signal on the basis of the position signal to control the actuator, wherein the controller calculates a current position and a current speed of the operating unit on the basis of the position signal and determines a first component of the actuator drive signal, the first component corresponding to the current position, by multiplying a sum of the current position and a product of the current speed and a coefficient by an elastic modulus.
