Patent ID: 7607786

Claim:
A light deflector, comprising: a substrate; a plurality of control members provided at edge parts of the substrate, the control members having upper parts where stoppers are situated; a fulcrum member provided on an upper surface of the substrate, the fulcrum member having a top part; a plate-shaped member movably provided in a space formed by the substrate, the fulcrum member and the stoppers, the plate-shaped member having a light reflection area and no fixed end; and a plurality of electrodes provided on the substrate, the electrodes facing the plate-shaped member; wherein the plate-shaped member is tilted and displaced by an electrostatic attraction force in a state where the fulcrum member is a center, so that a reflection direction of a light flux incident on the light reflection area is changed and thereby light deflection is performed; and wherein the substrate includes a contact part formed thereon which contacts the plate-shaped member, the contact part including an upper layer and a lower layer, and the upper layer and not the lower layer is made of a main ingredient which is a high melting point metal element.
