<P>PROBLEM TO BE SOLVED: To provide a piezoelectric apparatus which assures excellent durability and is provided with a guide mechanism on a piezoelectric material. <P>SOLUTION: The piezoelectric apparatus 1 is provided with a rectangular plate unimorph element 11, a holding member 12 for holding one end in the longitudinal direction of the unimorph element 11, and a guide 13 which is located on the side to which the unimorph element 11 is bent when a force to bend the unimorph is applied thereto. Since the unimorph element 11 is deformed along the shape of bending surface of the guide member 13, the concentrated stress at the area near the holding member 12 is controlled. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
