ABSTRACT:
A piezoelectric/electrostrictive device includes a ceramic substrate having a pair of mutually opposing thin plate sections, a fixed section for supporting the thin plate sections, and movable sections disposed at ends of the pair of thin plate sections. The piezoelectric/electrostrictive device has a portion of each movable section opposed to the fixed section, the portion being formed in a stepped form so that respective attachment surfaces are provided with steps. Cutouts (cutaways) are formed at portions of an inner wall of the fixed section near the thin plate sections. Further, steps are provided on inner walls of the cutouts disposed on the sides of the thin plate sections.
