Document Type and Number:
WIPO Patent Application WO/2020/255977
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an electrostatic actuator with which it is possible to generate a large electrostatic force even when configured from a ribbon-shaped electrode film. An electrostatic actuator 10, 20 provided with a ribbon-shaped first electrode film 11 and a ribbon-shaped second electrode film 12, wherein: a plurality of first electrodes 1 formed by the first electrode film 11 and a plurality of second electrodes 2 formed by the second electrode film 12 are laminated in an overlapping manner between one end 13 and the other end 14 of the electroconductive actuator 10, 20; and the plurality of first electrodes 1 include a pair of end part electrodes 1a, which are adjacent to each other along the direction in which the first electrode film 11 extends in a ribbon shape and which are respectively located at the one end 13 and the other end 14 when laminated, and intermediate electrodes 1b that are located between the end part electrodes 1a when laminated.
