METHOD FOR MANUFACTURING PIEZOELECTRIC MATERIAL, PIEZOELECTRIC ELEMENT, LIQUID EJECTING HEAD, LIQUID EJECTING APPARATUS, ULTRASONIC SENSOR, PIEZOELECTRIC MOTOR, AND POWER GENERATOR
PROBLEM TO BE SOLVED: To provide: piezoelectric material that reduces environmental loads, and has high piezoelectric characteristics and dielectric characteristics in a wide use environment temperature range and also high Curie temperature; a piezoelectric element using the piezoelectric material; a liquid ejecting head; a liquid ejecting apparatus; an ultrasonic sensor; a piezoelectric motor; and a power generator.SOLUTION: Piezoelectric material contains: a first component which comprises complex oxide having a perovskite structure that is rhombohedral crystal in a single composition and has Curie temperature of Tc1; a second component which comprises complex oxide having the perovskite structure that is crystal other than the rhombohedral crystal in the single composition and has the Curie temperature of Tc2; and a third component which comprises complex oxide having the perovskite structure that is the same crystal system as the second component in the single composition and has the Curie temperature of Tc3. The Tc1 is higher than the Tc2, and the Tc3 is higher than the Tc1.
