A piezoelectric/electrostrictive device includes: a driving portion which is driven by displacement of a piezoelectric/electrostrictive element, a movable portion which operates on the basis of a drive of the driving portion, and a fixed portion for supporting the above driving portion and movable portion. It has a driving portion including thin plates facing each other and a thin film piezoelectric/electrostrictive element formed on the surface of at least one of the thin plates, and the above fixed portion and the above movable portion are joined by the driving portion. In this piezoelectric/electrostrictive element, the movable portion can largely be displaced, and it is not easily affected by a harmful vibration in operation, and it is excellent in mechanical strength, handling efficiency, impact resistance, and moisture resistance.
