Beschreibung
Zusammenfassung:	A light deflector includes a reflector having a reflecting surface; a first movable unit having one end coupled to the reflector; a second movable unit having one end coupled to the reflector, the reflector disposed between the first movable unit and the second movable unit; a first piezoelectric element on the first movable unit; a second piezoelectric element on the second movable unit; a first supporting part coupled to the other end of the first movable unit; a second supporting part coupled to the other end of the second movable unit; an input part configured to receive voltage to be applied to at least the second piezoelectric element; and a wire electrically connecting the second piezoelectric element and the input part through the reflector configured to transmit the voltage to the second piezoelectric element. A passage area is provided through which light reflected by the reflector passes.
