CRYSTAL-ORIENTED PIEZOELECTRIC CERAMIC, PIEZOELECTRIC ELEMENT, AND METHOD FOR MANUFACTURING CRYSTAL-ORIENTED PIEZOELECTRIC CERAMIC

摘要

A crystal-oriented piezoelectric ceramic containing a principal component having a relative density of 95.0%-98.5%, the principal component being represented by the general formula: (1-s) A1B1O3-sBaMO3 (where A1 is at least one species of element selected from alkali metals, B1 is at least one species of element of transition metal elements and contains Nb, M is at least one species of element of the 4A group and contains Zr, and 0.05 < s ≦̸ 0.15).
