Abstract
Official abstract text for this publication.
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): xBaTiO 3 -yBiFeO 3 -zBi(M 0.5 Ti 0.5 )O 3 (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.
