Patent ID: 7579747

Claim:
An electrostatic actuator comprising: a stator having a plurality of protruding electrodes formed on a surface of a base material, the surface serving as a counter surface; and a mover disposed so as to face the stator, the mover having a plurality of protruding electrodes formed on a surface of a base material, the surface serving as a counter surface, a side surface of each of the protruding electrodes of the stator facing a side surface of a corresponding one of the protruding electrodes of the mover; wherein planar electrodes are formed on at least one of the counter surface of the stator and the counter surface of the mover in a portion other than a portion where the protruding electrodes are formed, and the planar electrodes face end surfaces of the protruding electrodes formed on the other of the counter surface of the stator and the counter surface of the mover.
