ABSTRACT:
In an electrostatic actuator, a stator element having electrodes formed on an insulation layer and a movable element having electrodes formed on an insulation layer. The movable element is arranged opposite to the stator element so as to be movable with respect to the stator element. The electrodes of the movable element and the stator element are connected together at every other electrode to provide two phases for the movable element and the stator element, respectively. An interval of the electrodes of the stator element is made unequal. The electrodes of the movable element are applied with a voltage of fixed polarity, while the electrodes of the stator element are applied with a voltage of switched-over polarity. A ground section is provided between adjacent ones of the electrodes of one of the movable element and the stator element and is continuously grounded.
