摘要

PROBLEM TO BE SOLVED: To provide a laminated piezoelectric element having a long life, in which the piezoelectric ceramic layer does not contain lead as a constituent element and the content ratio of silver in the internal electrode layer is high. SOLUTION: The main component of the piezoelectric ceramic layer does not contain lead as a constituent element and is represented by the composition formula LixNayK1-x-yNbO3 (where 0.02 x≤0.1, 0.02 x + y≤1). The perovskite-type compound is used, and the internal electrode layer is made of a metal containing 80% by mass or more of silver, and is a laminated piezoelectric ceramic containing co-material particles made of ceramics.
