In a state in which a position sensor for focusing is viewed in the direction of an optical axis, a line connecting the position sensor for focusing to the optical axis is set as a first reference line and a line orthogonal to the first reference line and passing through the optical axis is set as a second reference line. The position sensor for focusing is disposed in a first region of the first region and a second region partitioned by the second reference line. An X-direction VCM and a Y-direction VCM are arranged in the second region. The influence of magnetism from the X-direction VCM and the Y-direction VCM on the position sensor for focusing is suppressed.
