ABSTRACT:
An electrostatic actuator includes a stationary element having a plurality of driving electrodes arranged in a predetermined direction and with predetermined spaces in an isolated state on an insulating supporter, a movable element, disposed in contact with the stationary element, electric wires connected to the driving electrodes of the stationary element, and a driving voltage control section to apply to the driving electrodes voltages which cause a change in the relative position of the first and second members by a Coulomb's force of static electricity between the stationary element and the movable element, which is produced by switching the voltages to the driving electrodes, wherein the driving voltage control section includes a power source of high voltage and direct current, a high voltage switching portion and a driving control portion; the power source including a transformer for raising the voltage of high frequency current signals, and a rectifier for rectifying an output of the transformer to obtain high positive and negative voltages of direct current.
