Abstract: Disclosed is an electrostrictive effect element comprising a columnar casing having openings on either end, laminated blocks with a laminated ceramic capacitor structure. The laminated blocks are stacked in the casing and electrically connected to each other and have a sufficient number of electrostrictive material layers formed to prevent mechanically damaged due to stress generated when a voltage is applied. The electrostrictive effect also includes means which is disposed outside the casing and made of a spring or the like for applying a compressive force to said laminated blocks in the lamination direction thereof, and engaging members which are engaged with said laminated blocks for applying a compressive force through said compression means to said laminated blocks.
