Abstract: An actuator device manufacturing method includes: a preparation step of preparing an actuator device including a support portion, a movable portion, a connection portion, and a metal member disposed such that a stress acts on the metal member when the movable portion oscillates; an oscillation step of oscillating the movable portion for a predetermined time; an acquisition step of acquiring a parameter related to a viscous resistance in a vibration of the movable portion; and a determination step of determining that the actuator device is qualified, when a difference between the parameter acquired in the acquisition step and a reference value corresponding to the parameter at a start of the oscillation step is a predetermined value or more in a direction in which the viscous resistance decreases, and determining that the actuator device is disqualified, when the difference is less than the predetermined value.

Abstract: An actuator device includes a support part, a movable part, a connecting part, a spiral coil provided to the movable part, a magnetic field generator, an external terminal provided to the support part; and a wiring connected to an inner end portion of the coil and the external terminal. The wiring includes a lead wiring connected to the external terminal, and a straddle wiring formed in a shape of a layer, provided to the movable part so as to straddle the coil, and connected to the inner end portion of the coil and the lead wiring. A thickness of the straddle wiring is smaller than a thickness of the coil. The straddle wiring is electrically insulated from the mirror surface.
