Abstract:
An optical deflector comprising:a movable plate having a reflection surface and an opposite surface opposite to the reflection surface; a support member including a confronting substrate which confronts the opposite surface of the movable plate; at least one elastic member having two ends, one end being supported by the support member and the other end being attached to the movable plate, and extending in a first direction extending from the one end to the other end; and driving member for driving the movable plate to rock with respect to the support member with using a second direction normal to the first direction as a rock axis, the confronting substrate having a contact area which defines a maximum deflection angle of the movable plate and restricts the rocking movement of the movable plate within the maximum deflection angle, and the contact area having a first and a second deflection position with which the movable plate is brought into contact when the driving member applies a driving force to the movable plate.
