    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.

    摘要： A piezoelectric/electrostrictive device includes 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 includes the cooling 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 the sub-step of holding the piezoelectric/electrostrictive device at a constant temperature lower than the firing temperature. The holding temperature is set within the range of temperatures at which high-temperature creep occurs in the metal of the electrode layer. Thus, residual stress in the piezoelectric/electrostrictive layer can be reduced.

    摘要： A piezoelectric body is provided, including (Bi½Na½)TiO3 as a main component which is obtained by forming and sintering powders. A heterogeneous phase, other than (Bi½Na½)TiO3 system perovskite phase, in the powders has a peak ratio relative to the strongest peak of the perovskite phase of 5% or lower as determined by powder X-ray diffraction. As a result, the frequency of the dielectric breakdown in a sintered piezoelectric body during polarization can be dramatically reduced to 0.1 to 2% of that experienced in prior art compositions The manufacturing yield can be increased, manufacturing costs can be reduced, and the overall reliability of products manufactured therefrom can be improved.

    摘要： A piezoelectric/electrostrictive element with improved moisture resistance while having less degradation in its piezoelectric/electrostrictive properties and a method of manufacturing such a piezoelectric/electrostrictive element are provided. A laminated vibrator of a piezoelectric/electrostrictive element has a structure in which an electrode film, a piezoelectric/electrostrictive film, another electrode film, another piezoelectric/electrostrictive film, and another electrode film are laminated one above the other. In the manufacture of the piezoelectric/electrostrictive element, the laminated vibrator and a counter electrode are immersed in an electrodeposition coating fluid containing a coating component so that the electrodeposition coating fluid is brought into contact with the surfaces of the laminated vibrator and the counter electrode. Thereafter, voltage is applied between an internal electrode film and the counter electrode to induce electrophoresis of the coating component toward a surface-exposed defect, whereby the coating material is selectively electrodeposited on the surface-exposed defect.
