Abstract:
A lens barrel includes first and second driving units configured to move first and second moving frames in an optical axis direction, and two correction driving sources configured to move the second moving frame in a direction perpendicular to an optical axis. Moving ranges in the optical axis direction of the first and second moving frames overlap with each other. The first and second moving frames are connected to a fixing portion of a fixed barrel by first and second flexible printed boards. One of the first and second driving units is located on a side of the optical axis opposite one of the second correction driving sources, and U-turn portions of the first and second flexible printed boards are located on a side of the optical axis opposite the other correction driving source, when viewed in the optical axis direction.
