Abstract
A first magnetic body is arranged between a coil and an image pickup element, and has an opening through which light directed from an imaging optical system toward the image pickup element passes. A second magnetic body is arranged at a position on the coil side with respect to the first magnetic body in an optical axis direction of the imaging optical system. The second magnetic body is arranged such that at least a portion thereof overlaps the first magnetic body when seen in the optical axis direction, at a position on the coil side with respect to the opening. The second magnetic body is made of a ferromagnetic material having higher relative permeability than that of the first magnetic body, and has a smaller area than that of the first magnetic body when seen in the optical axis direction.
