Classification: CPC G  B  H | IPC G  H

Claim 0:
1. An optical deflector comprising:
a reflective plate;
a pair of shaft portions extending in a direction of a rotation axis of the reflective plate and determining the rotation axis of the reflective plate;
a pair of beam portions supporting the pair of shaft portions while extending to intersect the rotation axis; and
drive elements rotating the reflective plate by deforming the beam portions,
wherein the drive elements are arranged in the beam portions and a size thereof in a direction orthogonal to the rotation axis at positions separated by a first distance from the reflective plate along an axial direction of the rotation axis is larger than a size in the direction orthogonal to the rotation axis at positions separated by a second distance from the reflective plate along the axial direction, the second distance being greater than the first distance.
