Abstract:
An optical unit includes a movable body, a fixed body surrounding the movable body, a turning support mechanism turnably supporting the movable body with respect to the fixed body, and a drive mechanism including a coil disposed on the movable body or the fixed body, and multiple magnets disposed on the other of the movable body and the fixed body at a position facing the coil. An end part in an optical axis direction of the coil is bent in a direction approaching a turning axis of the movable body, and the magnets are disposed side by side so that faces of the magnets facing the coil become approximately parallel to the coil when viewed in a direction of the turning axis in comparison with a case that the magnets are arranged along the optical axis direction.
