Abstract
An optical unit with a shake correction function may include an optical module having a movable body holding an optical element, a support body swingably supporting the movable body around two axial lines perpendicular to an optical axis of the optical element, and a swing drive mechanism structured to be capable of reciprocatedly swinging the movable body with respect to the support body around the two axial lines, and a rolling correction drive mechanism structured to be capable of reciprocatedly turning the optical module around the optical axis. The rolling correction drive mechanism includes a single phase motor in which the number of salient poles of a stator core around which a stator coil is wound is two times of the number of magnetic poles of a rotor magnet.
