Abstract
A piezoelectric/electrostrictive device including a pair of mutually opposing thin plate sections, a movable section, and a fixation section for supporting the thin plate sections and the movable section. At least one piezoelectric/electrostrictive element is arranged on the pair of thin plate section, and a hole is formed by both inner walls of the pair of thin plate sections, an inner wall of the movable section, and an inner wall of the fixation section. The pair of thin plate sections are previously bent in directions to make mutual separation so that they have an outwardly convex configuration.
