摘要： A piezoelectric/electrostrictive device is provided, including a substrate, an electrode layer adhering to the surface of the substrate, and a piezoelectric/electrostrictive layer adhering to the electrode layer. The electrode layer is deformed by high-temperature creep. A method for manufacturing the piezoelectric/electrostrictive device is provided including a step of cooling the piezoelectric/electrostrictive device, after firing, at a temperature decreasing rate of at least the rate of natural cooling. The cooling step includes a sub-step of holding the piezoelectric/electrostrictive device at a constant holding temperature that is lower than the firing temperature. The holding temperature is within a range of temperatures at which high-temperature creep occurs in the metal of the electrode layer so that residual stress in the piezoelectric/electrostrictive layer can be reduced.

摘要： A piezoelectric/electrostrictive element includes a laminated vibrator made of laminations of a piezoelectric/electrostrictive film and an electrode film, with the electrode film having an internal electrode film. The piezoelectric/electrostrictive element has a coating formed on a part of a surface of the laminated vibrator so that the coating selectively and completely covers a defect that would otherwise be exposed on the surface of the vibrator before the coating coats the defect. The defect extends to the internal electrode film and the remainder of the surface of the laminated vibrator is free of the coating.
