Abstract:
1. A matrix type piezoelectric/electrostrictive actuator comprising a plurality of piezoelectric/electrostrictive elements, each including a piezoelectric/electrostrictive body and at least one pair of electrodes formed only on side surfaces of said piezoelectric/electrostrictive body, said side surfaces being formed as sintered surfaces, and each disposed on a ceramic substrate and having an upper surface plane that is generally perpendicular with respect to an upper surface plane of said ceramic substrate, wherein said piezoelectric/electrostrictive elements are joined to said ceramic substrate as respective unified bodies that are two-dimensionally arranged independently of each other, and said actuator is activated by displacement of said piezoelectric/electrostrictive bodies.
