Abstract:
In a unit with shake correction function, a driving magnet and a driving coil which constitute a rolling drive mechanism are arranged on an outer side of a radial direction with respect to a disposition space for an optical module that is provided in a movable body. Therefore, since there is no need to arrange the disposition space and the rolling drive mechanism to be deviated from each other in an optical axis direction, it is possible to make the unit with shake correction function thin in the optical axis direction. Further, in the rolling drive mechanism, since the driving magnet and the driving coil face each other in the optical axis direction, a magnetic field of the rolling drive mechanism does not easily enter the disposition space for the optical module. Consequently, magnetic interference between the movable body and the rolling drive mechanism can be suppressed.
