Abstract
A first image blur correction device includes an imaging-element holding-member to which an imaging-element is fixed, a housing that supports the imaging-element holding-member to be movable in a direction X perpendicular to an optical axis of a lens device, and a first drive mechanism that generates thrust of moving the imaging-element holding-member in the direction X. The first drive mechanism includes a first magnet that is fixed to the housing and in which a direction connecting both magnetic poles is parallel to the direction X, and a first coil that is fixed to the imaging-element holding-member to face the first magnet. In a state where the imaging-element holding-member is at a reference position where the optical axis of the lens device coincides with a center of the imaging-element, a position of a first magnet center in the direction X and a first coil central axis deviate from each other.
