Piezoelectric/electrostrictive device and method of manufacturing same

摘要

A piezoelectric/electrostrictive device (10) comprises a pair of mutually opposing thin plate sections (12a, 12b) and a fixation section (14) for supporting the thin plate sections (12a, 12b); and a piezoelectric/electrostrictive element (18a, 18b) arranged on each of the pair of thin plate sections (12a, 12b); wherein movable sections (20a, 20b) have mutually opposing end surfaces (34a, 34b); and a distance (Lc) between the end surfaces (34a, 34b) is not less than a length (Df) of the movable section (20a, 20b).
