The purpose of the present invention is to provide an actuator which can realize a further reduction in height. Provided is an actuator which performs shake correction by tilting a driven member using the drive force of a voice coil motor, wherein a support part tiltably supports a movable body with respect to a fixed body in which one from between a magnet part and a coil part is disposed on a base member, the movable body being configured so that the other from between the magnet part and the coil part is disposed on a frame-shaped retaining member on which the driven member is mounted. The retaining member has steps, and these steps enable a mounting site of the driven member to be closer to the base member than the disposition site of the one from between the coil part and the magnet part.
