Abstract
A piezoelectric/electrostrictive device includes a basehaving a pair of movable partsopposing each other and a connecting partthat connects movable partswith each other at one end thereof as well as piezoelectric/electrostrictive elementsdisposed on the side surfaces of movable partsof base. The piezoelectric/electrostrictive device is constructed in a simple structure with fewer components. Baseis integrally formed in an open-box shape or in a horseshoe shape by bending one sheet of band-shaped flat plate. Movable partsextend for a predetermined length from respective ends of connecting partto the other ends. The other ends of movable partsconstitute a mounting site for mounting a component to be controlled or a component to be tested.
