A piezoelectric/electrostrictive device (10) comprises a pair of mutually opposing thin plate sections (16a, 16b), a movable section (20), and a fixation section (22) for supporting the thin plate sections (16a, 16b) and the movable section (20); a piezoelectric/electrostrictive element (24a, 24b) arranged on at least one thin plate section (16a, 16b) of the pair of thin plate sections (16a, 16b); and a hole (12) formed by both inner walls of the pair of thin plate sections (16a, 16b), an inner wall (20a) of the movable section (20), and an inner wall (22a) of the fixation section (22), wherein a central portion of the movable section (20) is cut off to form mutually opposing end surfaces (36a, 36b) in the movable section (20). <IMAGE> |
