Abstract
According to one embodiment, an electrostatic actuator includes an electrode unit, a conductive film body unit, a plurality of first urging units, and a plurality of second urging units. The electrode unit is provided on a substrate. The conductive film body unit is provided opposing the electrode unit. The plurality of first urging units are provided at a first circumferential edge portion of the conductive film body unit to support the film body unit. The plurality of second urging units are provided at a second circumferential edge portion opposing the first circumferential edge portion to support the film body unit. The electrode unit and the conductive film body unit contact or separate by the electrode unit being set to a voltage having a prescribed value. The plurality of first urging units have mutually different rigidities, and the plurality of second urging units have mutually different rigidities.
