ABSTRACT:
The piezoelectric/electrostrictive properties and mechanical durability of a piezoelectric/electrostrictive ceramic can be improved. A piezoelectric/electrostrictive device has a laminated structure in which an electrode film, a piezoelectric/electrostrictive film, an electrode film, an piezoelectric/electrostrictive film, and an electrode film are laminated in the order mentioned on a thin portion of a substrate. The piezoelectric/electrostrictive films are ceramic films with a matrix of perovskite oxide that contains lead (Pb) as an A-site component and nickel (Ni), aluminum (Al), niobium (Nb), zirconium (Zr), and titanium (Ti) as B-site components. The piezoelectric/electrostrictive films are formed by firing as a unit the substrate that contains aluminum oxide and an intermediate coating film of perovskite oxide that contains components other than aluminum so that aluminum oxide is diffused from the substrate to the intermediate coating film.
