Piezoelectric material, piezoelectric element, liquid discharge head, ultrasonic motor, and dust removing device
Provided is a piezoelectric material that achieves both high piezoelectric performance and high Curie temperature. In addition, provided are a piezoelectric element, a liquid discharge head, an ultrasonic motor, and a dust removing device, which use the piezoelectric material. The piezoelectric material includes a perovskite-type metal oxide that is expressed by the following general formula (1): xBaTiO3-yBiFeO3-zBi(M0.5Ti0.5)O3 (1), where M represents at least one type of element selected from the group consisting of Mg and Ni, x satisfies 0.25≰x≰0.75, y satisfies 0.15≰y≰0.70, z satisfies 0.05≰z≰0.60, and x+y+z=1 is satisfied.
