A piezoelectric/electrostrictive device includes a base 11 having a pair of movable parts 11 a, 11 b opposing each other and a connecting part 11 c that connects movable parts 11 a, 11 b with each other at one end thereof as well as piezoelectric/electrostrictive elements 12 a, 12 b disposed on the side surfaces of movable parts 11 a, 11 b of base 11 . The piezoelectric/electrostrictive device is constructed in a simple structure with fewer components. Base 11 is integrally formed in an open-box shape or in a horseshoe shape by bending one sheet of band-shaped flat plate. Movable parts 11 a, 11 b extend for a predetermined length from respective ends of connecting part 11 c to the other ends. The other ends of movable parts 11 a, 11 b constitute a mounting site for mounting a component to be controlled or a component to be tested.
