PIEZOELECTRIC ELEMENT AND STACKED PIEZOELECTRIC ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide a tight piezoelectric element or stacked piezoelectric element of good piezoelectric characteristics in which an electrode layer and a piezoelectric sintered body main component of niobic acid alkali metal are provided by simultaneous sintering.

SOLUTION: A stacked piezoelectric element 1 comprises a piezoelectric sintered body layer 2 whose main component is niobic acid alkali metal, and internal electrode layers 3A and 3B which are formed by simultaneous sintering with it and laminated alternately. The internal electrode layers 3A and 3B comprise Pt, and the piezoelectric sintered body layer 2 is tight.
