Method of manufacturing actuator

A method of manufacturing an actuator in which a cylindrical dielectric elastomer layer and cylindrical electrode layers have been concentrically laminated in such a manner that the electrode layers respectively face an inner circumferential surface and an outer circumferential surface of the dielectric elastomer layer, comprising:

• a first electrode layer forming step in which, with a layer forming jig having a shaft section, an electrode material is provided to an outer circumferential surface of the shaft section, thereby forming the electrode layer;
• a dielectric elastomer layer forming step in which a sheet-like or paste-like dielectric elastomer material is provided to an outer circumferential surface of the electrode layer, thereby forming the dielectric elastomer layer;
• and
• a second electrode layer forming step in which the electrode material is provided to the outer circumferential surface of the dielectric elastomer layer, thereby forming the electrode layer.
