    PROBLEM TO BE SOLVED: To provide a piezoelectric ceramic composition used for a piezoelectric device which is suitable for use in a high temperature environment.SOLUTION: The piezoelectric device is provided with: a piezoelectric ceramic layer that is obtained by firing a piezoelectric ceramic composition which contains a perovskite composition and an Ag component; and a conductor layer that sandwiches the piezoelectric ceramic layer, in which Ag is segregated in voids in a sintered body of the perovskite composition in the piezoelectric ceramic layer. Preferably, the piezoelectric ceramic composition contains a perovskite composition which is represented by (PbRe){ZrTi(NiNb)(ZnNb)}O[where Re is La and/or Nd, and a-e and x satisfy the following requirements: 0.95≤a≤1.05, 0≤x≤0.05, 0.35≤b≤0.45, 0.35≤c≤0.45, 0

    【課題】高温環境下での使用に好適な圧電デバイスに用いられる圧電磁器組成物を提供する。【解決手段】圧電デバイスは、ペロブスカイト組成物と、Ａｇ成分とを含有する圧電磁器組成物を焼成して得られる圧電磁器層と該圧電磁器層を挟持する導体層とを備え、圧電磁器層はペロブスカイト組成物の焼結体中の空隙にＡｇが偏析している。圧電磁器組成物は、（Ｐｂａ・Ｒｅｘ）｛Ｚｒｂ・Ｔｉｃ・（Ｎｉ１／３Ｎｂ２／３）ｄ・（Ｚｎ１／３Ｎｂ２／３）ｅ｝Ｏ３［式中、Ｒｅは、Ｌａ及び／又はＮｄであり、ａ〜ｅ、ｘは次の要件を満たす。０．９５≦ａ≦１．０５、０≦ｘ≦０．０５、０．３５≦ｂ≦０．４５、０．３５≦ｃ≦０．４５、０＜ｄ≦０．１０、０．０７≦ｅ≦０．２０、ｂ＋ｃ＋ｄ＋ｅ＝１］で表わされるペロブスカイト組成物と、酸化物換算でペロブスカイト組成物に対し０．０５〜０．３質量％のＡｇ成分とを含有するものが好ましい。【選択図】図１
