Abstract
An optical deflector capable of making a swing angle of a reflective plate larger is provided. In drive elements, since a size in the Y direction at first positions separated by a first distance from the reflective plate is larger than a size in the Y direction at second positions separated by a second distance from the reflective plate, the second distance being greater than the first distance, it is possible to increase displacement of tips of beam portions at the first positions and to make a swing angle of the reflective plate large by increasing a generated force of the entire beam portions.
