Abstract
An actuator comprises a support body including a coil having a winding part and a lead part, a coil holder and a board supported by the coil holder, a movable body having a magnet, and a magnetic drive mechanism structured to relatively move the support body and the movable body. The coil holder has a coil holding part holding the winding part and a board support part supporting the board. A board surface of the board is provided with a land with which the lead part is connected. The board support part has a recessed part at a position overlapping with the board when viewed in a direction along the board surface, and the lead part is extended from the winding part to the land via the recessed part and is provided with a resiliently bent portion which is resiliently bent in an inside of the recessed part.
