PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a lead-free piezoelectric material having a high piezoelectric constant and a high mechanical quality factor in a wide operating temperature range.SOLUTION: A piezoelectric material includes a perovskite-type metal oxide represented by following general formula (1): (BaCa)(TiZr)O(1.00≤a≤1.01, 0.125≤x<0.155, and 0.041≤y≤0.074) as a main component. In the piezoelectric material, the metal oxide contains Mn, and the Mn content is ≥0.12 pts. wt and ≤0.40 pts. wt on a metal basis with respect to the 100 pts.wt metal oxide.
