PCT No. PCT/JP91/00497 Sec. 371 Date Feb. 6, 1992 Sec. 102(e) Date Feb. 6, 1992 PCT Filed Apr. 16, 1991 PCT Pub. No. WO91/16757 PCT Pub. Date Oct. 31, 1991.An electrostatic actuator comprising: a first member (1) having a plurality of belt-like electrodes (4) insulated from one another and disposed in a predetermined direction with predetermined gaps between them; a second member (10) constituted by a resistance body on the opposed surface thereof coming into contact with the surface of the first member (1); and control means (11) capable of changing an impressed voltage to be applied to each of a plurality of belt-like electrodes disposed on the first member; the control means (11) being constituted so as to move the first and second members relative to each other by applying a predetermined voltage pattern consisting of a pulse voltage to the belt-like electrodes. The resistance body of the second member is selected so that the value of the time constant, which is primarily determined by a volume resistivity and dielectric constant of the material constituting the resistance body, becomes twice the time necessary four at least one of the first and second members to move relative to the other by a distance corresponding to the length between the electrodes.
