Piezoelectric ceramics, a method of manufacturing a piezoelectric ceramic, a piezoelectric element, a liquid discharge head, a liquid discharge apparatus, an ultrasonic motor, an optical apparatus, a vibration device, a dust removing device, an imaging device, a piezoelectric acoustic component and an electronic device,
Provided is a piezoelectric ceramics that can achieve both high piezoelectric performance and a high Curie temperature. Also provided are a piezoelectric element, a liquid discharge head, an ultrasonic motor, and a dust removing device, which use the piezoelectric ceramics. The piezoelectric ceramics include a perovskite-type metal oxide expressed by a general formula (1): xBaTiO3-yBiFeO3-zBi(M0.5Ti0.5)O3, where M represents at least one type of element selected from the group consisting of Mg and Ni, x satisfies 0.40x0.80, y satisfies 0y0.30, z satisfies 0.05z0.60, and x+y+z=1 is satisfied, and are oriented in a (111) plane in a pseudocubic expression.
