PROBLEM TO BE SOLVED: To provide a piezoelectric/electrostrictive device capable of being formed into a small size, unlikely to be influenced by detrimental vibrations, capable of making quick response, having a high mechanical strength, and excellent in the handling easiness, shock resistance, and moistureproofness. SOLUTION: A pair of thin plate parts 12a and 12b confronting each other and a stationary part 14 to support the thin plate parts 12a and 12b are formed into a single piece by ceramics, and an object 18 is attached between the forefront parts of the thin plate parts 12a and 12b, and piezoelectric/electrostrictive elements 20a and 20b are installed on the side faces of the thin plate parts 12a and 12b, wherein the area of those surfaces of the object 18 opposing to the thin plate parts 12a and 12b is set greater than the area of those surfaces 34a and 34b of the thin plate parts 12a and 12b where the object is to be mounted.
