Abstract
An optical deflector includes a magnet unit and a movable plate unit. The movable plate unit has an inner movable plate having a reflecting surface, an outer movable plate, two inner torsion bars connecting the inner and outer movable plates, a support located outside the outer movable plate, and two outer torsion bars connecting the outer movable plate and support. The movable plate unit has two inner wirings, each of which has an inner drive wiring portion that extends along by a periphery of the inner movable plate and two inner extracted wiring portions extending from two ends of the inner drive wiring portion. The two inner drive wiring portions are located substantially line-symmetrically with respect to the first axis. The two inner extracted wiring portions are located substantially line-symmetrically with respect to the second axis. Currents of the same direction are applied to the two inner drive wiring portions.
