ABSTRACT:
An object of the present invention is to provide an electrostatic actuator that can be easily assembled and suitably mass-produced and that can implement requirements of both the steady, smooth and stable operation and the enhanced reliability. The present invention is also directed to a method of activating such an electrostatic actuator, and a camera module used with the same.
