Abstract: A lens holding unit is held so that it can relatively move with respect to a base part to a direction vertical to an optical axis direction. The lens holding unit has a lens holder, a magnet part, and a spring. The lens holder has a first coil. The magnet part has a first magnet part which includes a first face facing to the first coil and a second magnet part which includes a second face vertical to the first face and constitutes a magnetic domain different from that of the first magnet part. These first magnet part and second magnet part are integrated.
