Abstract
There is provided a polymeric actuator including: a pair of facing portions located so as to face each other; and a folded portion through which one end portions of the pair of facing portions are coupled to each other, wherein the pair of facing portions and the folded portion are composed of an inner electrode layer, an electrolyte layer, and an outer electrode layer which are laminated in order from an inside. Therefore, the displacements are generated in the pair of facing portions, respectively, to be added to each other, and the displacement is generated in the folded portion as well due to the bending. As a result, the large displacement is generated as a whole. Thus, it is possible to increase the displacement amount after the simplification of the structure is realized.
