Patent ID: 11848625

Abstract:
The present invention is directed to providing an electrostatic actuator that can generate a large electrostatic force even if composed of a ribbon-shaped electrode film.In an electrostatic actuator 10, 20 including a ribbon-shaped first electrode film 11 and a ribbon-shaped second electrode film 12, a plurality of first electrodes 1 formed of the first electrode film 11 and a plurality of second electrodes 2 formed of the second electrode film 12 are folded and laminated between one end 13 and the other end 14 of the electrostatic actuator 10, 20, and the plurality of first electrodes 1 include a pair of end electrodes 1a that are adjacent to each other in a direction in which the first electrode film 11 extends in a ribbon shape and are respectively positioned at the one end 13 and the other end 14 when laminated and at least one intermediate electrode 1b that is positioned between the end electrodes 1a when laminated.
