The surfaces of the magnets opposed to the movable coil are set as magnetic flux generating surfaces. In a cylindrical part disposed such that the axis direction thereof matches the optical axis direction, the mobile body is moved in the optical axis direction inside a cylindrical part. The arraying direction of the yoke and the magnets is set as the circumferential direction of the cylindrical part.
