Abstract: An actuator includes a plurality of laminated electrode sheets, and adhesive layers provided between the electrode sheets adjacent to each other. Each electrode sheet includes an elastomer layer, and an electrode provided on the elastomer layer. The plurality of electrode sheets are laminated such that the elastomer layer and the electrode are alternately located, and the adhesive layer is thinner than the electrode.

Abstract: [Object] An actuator includes an actuator body that includes a first surface and a second surface that face each other; a first constraining member that is provided on the first surface, and constrains the first surface from expanding and contracting; and a second constraining member that is provided on the second surface, and constrains the second surface from expanding and contracting. The actuator body includes a first electrode, a second electrode that faces the first electrode, and an elastomer layer that is provided between the first electrode and the second electrode. The first electrode is a pattern electrode. The first constraining member and the second constraining member are provided correspondingly to the first electrode.
