Abstract

The present invention employs an actuator including: a movable portion connected to a reflecting member having a reflective surface; a movable comb electrode disposed at a distance from the reflecting member, supported by the movable portion, and extended in a direction parallel to the reflective surface; a stationary comb electrode supported by a supporting portion, extends in the direction parallel to the reflective surface, and disposed alternately with the movable comb electrode; and a voltage controller that applies a voltage to the movable comb electrode and the stationary comb electrode to displace the movable comb electrode and the movable portion in a direction normal to the reflective surface. A portion that supports the movable comb electrode and a portion that supports the stationary comb electrode are disposed such that the movable comb electrode and the stationary comb electrode pass each other.
