It consists of an external yoke that fixes a permanent magnet placed opposite to the center pole through a yoke, and the movable coil moves in forward and reverse directions around the center of the set movement range, and when moving, the movable coil moves at the center position. In a voice coil type motor having an intersection where the end portion is located, a pair of grooves are formed at symmetrical positions around the center of the movement range, excluding the relative position of the intersection on the magnet facing surface of the center pole. A voice coil type motor characterized by:
