PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, LIQUID DISCHARGING HEAD, ULTRASONIC MOTOR AND DUST REMOVING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric material having both high piezoelectric performance and a high Curie temperature, and to provide a piezoelectric element, a liquid discharging head, an ultrasonic motor and a dust removing apparatus using the same.

SOLUTION: The piezoelectric material comprises a perovskite type metal oxide represented by general formula (1): xBaTiO3-yBiFeO3-zBi(M0.5Ti0.5)O3wherein M is at least one element selected from Mg and Ni, and x, y and z denote a numeral value having ranges of 0.25≤x≤0.75, 0.15≤y≤0.70, and 0.05≤z≤0.60, provided that x+y+z=1.
