    The piezoelectric ceramic composition contains, as a main component, a potassium sodium niobate-based perovskite-type composite oxide represented by the compositional formula ABO3. In addition, the piezoelectric ceramic composition contains Bi at the A site and Zr at the B site. Further, the piezoelectric ceramic composition has a segregation portion located within the crystal grains. At least one of Zr and Bi is non-uniformly distributed in the segregation part.

    压电陶瓷组合物是作为主成分而包含以组成式ABO3表示的铌酸钾钠类的钙钛矿型复合氧化物的压电陶瓷组合物。此外，压电陶瓷组合物在A位点包含Bi，在B位点包含Zr。进而，压电陶瓷组合物具有位于晶粒内的偏析部。Zr以及Bi中的至少一者不均匀地分布于偏析部。
