Abstract
A first conductive polymer film, a plate-shaped first porous member, a second conductive polymer film, and a plate-shaped second porous member are stacked on one another, and the adjacent members are connected with each other on first end portions so as to form a zigzag pattern. The first and second porous members each have an ionic solution injected thereinto so as to function as an electrolyte retention layer, so that operations can be carried out with tensions being always maintained upon both of the expansion and the contraction, and rigidity and a driving force can be exerted in both of the contracting and expanding directions.
