PIEZOELECTRIC CERAMICS, MANUFACTURING METHOD THEREFOR, PIEZOELECTRIC ELEMENT, LIQUID DISCHARGE HEAD, ULTRASONIC MOTOR, AND DUST REMOVAL DEVICE
Provided are a barium titanate-based piezoelectric ceramics having satisfactory piezoelectric performance and a satisfactory mechanical quality factor (Qm), and a piezoelectric element using the same. Specifically provided are a piezoelectric ceramics, including: crystal particles; and a grain boundary between the crystal particles, in which the crystal particles each include barium titanate having a perovskite-type structure and manganese at 0.04% by mass or more and 0.20% by mass or less in terms of a metal with respect to the barium titanate, and the grain boundary includes at least one compound selected from the group consisting of Ba4Ti12O27 and Ba6Ti17O40, and a piezoelectric element using the same.
