Abstract: An actuator device includes a support portion; a first movable portion; a first torsion bar portion coupling the first movable portion to the support portion to be swingable around a first swing axis; and a wiring disposed on the first torsion bar portion. The torsion bar portion is of a meandering shape including a plurality of straight sections extending in a first direction along the first swing axis and juxtaposed in a second direction intersecting with the first direction, and a plurality of turnover sections alternately coupling two ends of the straight sections. The plurality of turnover sections have a curved shape. The wiring includes wiring sections embedded in grooves formed in the turnover sections.

Abstract: A torsion bar portion is of a meandering shape including a plurality of straight sections and a plurality of turnover sections. The plurality of straight sections extends in a first direction along a swing axis and is juxtaposed in a second direction intersecting with the first direction. The plurality of turnover sections alternately couples two ends of the straight sections. Wiring is disposed on the torsion bar portion. The wiring includes first wiring sections and second wiring sections. The first wiring sections include damascene wiring sections that are disposed so as to be embedded in grooves formed in the turnover sections and that are made of a first metal material including Cu. The second wiring sections are disposed on the straight sections and are made of a second metal material more resistant to plastic deformation than the first metal material.

Abstract: A mirror drive device includes a support part, a movable part, a permanent magnet forming a magnetic field in the periphery of the movable part, and a circuit board disposed between the support part and the permanent magnet in a facing direction of a pair of principal surfaces of the movable part so as to cause the movable part to be positioned at an inside of the circuit board when viewed in the facing direction. The movable part includes a mirror disposition portion, a mirror disposed and a drive coil so as to face the permanent magnet. The support part includes a base portion connected to a connection member and a reinforcing portion extending from the base portion toward a side away from the permanent magnet and the circuit board. The drive coil is connected to electrodes by lead-out conductors.
