摘要： In the manufacture of a laminated piezoelectric/electrostrictive element by lamination of a piezoelectric/electrostrictive film and an electrode film containing either platinum or an alloy composed mainly of platinum and having a thickness of 2.0 µm or less, both or either one of yttrium oxide (Y 2 O 3 ) and cerium oxide (CeO 2 ) is added to the electrode film or the piezoelectric/electrostrictive film, and the electrode film and the piezoelectric/electrostrictive film are fired simultaneously. This simultaneously achieves a reduced thickness and improved thermal resistance of the electrode film and a reduced change in piezoelectric/electrostrictive properties with time, thereby producing a piezoelectric/electrostrictive element with good initial piezoelectric/electrostrictive properties and with a small change in the piezoelectric/electrostrictive properties with time.
摘要翻译：在通过层压压电/电致伸缩膜和包含铂或主要由铂组成的厚度为2.0μm或更小的合金的电极膜制造层压压电/电致伸缩元件时，氧化钇（ Y 2 O 3）和氧化铈（CeO 2）添加到电极膜或压电/电致伸缩膜中，并同时烧制电极膜和压电/电致伸缩膜。这同时实现了电极膜的减小的厚度和改善的热阻，并且减小了压电/电致伸缩特性随时间的变化，由此产生具有良好的初始压电/电致伸缩特性并且压电/电致伸缩性变化小的压电/电致伸缩元件随着时间的推移。

摘要： In a piezoelectric element comprising a first electrode 2 provided on a substrate 1, a piezoelectric material 3 provided on the first electrode 2 and a second electrode 4 provided on the piezoelectric material 3, the piezoelectric material 3 is configured so as to have a perovskite type crystal structure which is represented by a formula ABO3 and in which the main component for the A site is Pb and the main components for the B site are Zr, Ti and Pb, and configured so that a ratio of Pb atoms to all atoms in the B site is more than 3% and not more than 30%. Namely, the piezoelectric material 3 is formed so as to contain Pb excessively and the excess Pb atoms are activated to be Pb during formation of the piezoelectric material 3 and then introduced into the B site.
