  "abstract": "A piezoelectric/electrostrictive device includes a base 11 having a pair of movable parts 11 a, 11 b opposing each other and a connecting part 11 c that connects movable parts 11 a, 11 b with each other at one end thereof as well as piezoelectric/electrostrictive elements 12 a, 12 b disposed on the side surfaces of movable parts 11 a, 11 b of base 11. The piezoelectric/electrostrictive device is constructed in a simple structure with fewer components. Base 11 is integrally formed in an open-box shape or in a horseshoe shape by bending one sheet of band-shaped flat plate. Movable parts 11 a, 11 b extend for a predetermined length from respective ends of connecting part 11 c to the other ends. The other ends of movable parts 11 a, 11 b constitute a mounting site for mounting a component to be controlled or a component to be tested.",
  "claims": [
    "1. A piezoelectric/electrostrictive device comprising: a base having a pair of movable parts that are arranged in parallel with each other to oppose each other and a connecting part that connects the two movable parts with each other at one end thereof; and a piezoelectric/electrostrictive element disposed on an outer side surface of at least one of the two movable parts in the base, wherein the base is integrally constructed from one sheet of band-shaped flat plate, the movable parts extend for a predetermined length from respective ends of the connecting part to other ends, and the base has a flat plate part disposed on an inner surface of the connecting part.",
    "2. The piezoelectric/electrostrictive device as claimed in claim 1, wherein the piezoelectric/electrostrictive element is shorter than the movable parts and is positioned at the other end of the movable parts.",
    "3. The piezoelectric/electrostrictive device as claimed in claim 1, wherein the base has a generally open-box shape that is open to the other end of the two movable parts.",
    "4. The piezoelectric/electrostrictive device as claimed in claim 1, wherein the flat plate part is formed by a flat-plate-shaped member bonded on the inner surface of the connecting part."
