Abstract: An optical unit for endoscope includes: a moving barrel which is a soft magnetic body, configured to hold a lens; a fixed barrel which is a non-magnetic body, configured to movably hold the moving barrel on an inner circumferential face; a pair of yokes arranged on an outer face of the fixed barrel; a coil wound around the outer face of the fixed barrel and a magnet arranged on a part in the circumferential direction, between the pair of yokes; and a magnetic body member with magnetism stronger than magnetism of the moving barrel, the magnetic body member being arranged on a part of the moving barrel in the circumferential direction, corresponding to the magnet.
