PIEZOELECTRIC ELEMENT, LIQUID DISCHARGE HEAD, ULTRASONIC MOTOR, AND DUST REMOVING DEVICE
A piezoelectric element having an improved piezoelectric constant is provided, and a liquid discharge head, an ultrasonic motor, and a dust removing device, each of which uses the above piezoelectric element, are also provided. A piezoelectric element at least includes a pair of electrodes and a piezoelectric material provided in contact with the pair of electrodes, the piezoelectric material is formed of an aggregate of crystal grains containing barium titanate as a primary component, and among the crystal grains of the aggregate, crystal grains at least in contact with the electrodes have dislocation layers in the grains. A liquid discharge head, an ultrasonic motor, and a dust removing device each use the above piezoelectric element.
