An optical unit includes a fixed body, a movable body having an optical module having an optical axis, a support portion arranged on the fixed body and supporting the movable body, and a swing mechanism that swings the movable body with respect to the fixed body. The support portion is located radially inside about the optical axis with respect to the swing mechanism. The optical unit further includes a protruding portion that is arranged on a first one of the movable body and the fixed body, and protrudes from the first one of the movable body and the fixed body toward a second one to interpose a gap between the movable body and the fixed body. A shortest distance between the protruding portion and the second one of the movable body and the fixed body is shorter than a shortest distance between the movable body and the fixed body.

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.
