摘要：
An optical deflector includes a mirror rotatable around a rotating shaft of the optical deflector, the mirror including a base made of metal and a reflective surface, the reflective surface being parallel to an axial direction of the rotating shaft of the mirror. The mirror has a length that is twice a length from a center of the rotating shaft to the reflective surface, which is shorter than a length of the reflective surface in the direction of the rotating shaft.
