Abstract
An electrostatic actuator includes a fixed electrode and a movable electrode arranged to face the fixed electrode. The movable electrode is configured to be displaceable with respect to the fixed electrode and a fixed portion. An attractive force acts between the movable electrode and the fixed portion. In the electrostatic actuator, a non-linear vibration of the movable electrode when a voltage is applied to the fixed electrode and the movable electrode is reduced by the attractive force acting between the movable electrode and the fixed portion.
