Abstract: The task of the present invention is to provide an inertial drive actuator having a small-size arrangement, without using a vibration substrate. The inertial drive actuator includes a coil, a movable body which is disposed in a direction in which, a magnetic flux of the coil is generated, and which is formed of a magnetic material having a surface facing the coil, and a displacement generator (piezoelectric element) which displaces the coil in a direction different from the direction in which the magnetic flux is generated. Moreover, the movable body is displaced relatively with respect to the displacement generator (piezoelectric element), along a direction of displacement of the displacement generator (piezoelectric element).
