摘要： An optical deflector including a support substrate, a movable member, a reflective face, and a mounting structure for fixing the support substrate thereto. The movable member is rotatably or swingingly supported by the support substrate through elastic support members. The reflective face is provided on the movable member and deflects light incident thereon when the movable member is swung relatively to the support substrate. In the optical deflector, neutral surfaces of bending in a direction of a normal to the reflective face in the elastic support member and the movable member are not present in the same plane, and the support substrate is fixed to the mounting structure at a face of the support substrate on a side of the neutral surface in the movable member opposite to a side of the neutral surface in the elastic support member.
