Abstract
The present invention provides an electrostrictive element capable of preventing breakdown of a dielectric film. An electrostrictive elementincludes a dielectric filmcomposed of an elastomer, a film electrodeformed inside a peripheral edge on at least one surface of the dielectric filmand capable of expanding and contracting so as to follow expansion and contraction of the dielectric film, and a frameto keep the dielectric filmin an expansion state. The film electrodeincludes portionshaving a lower conductivity or a portionhaving a higher rigidity than the other portion on a portion to be subjected to a greater total stress of a mechanical stress and an electrical stress than the other portion of the dielectric film
