ORIENTED PIEZOELECTRIC CERAMIC, PIEZOELECTRIC ELEMENT, LIQUID DISCHARGE HEAD, ULTRASONIC MOTOR, AND DUST REMOVING DEVICE
Provided is an oriented piezoelectric ceramic of satisfactory piezoelectricity, which includes a metal oxide represented by (1−x)NaNbO3-xBaTiO3. Also provided are a piezoelectric element using the oriented piezoelectric ceramic which includes the metal oxide represented by (1−x)NaNbO3-xBaTiO3, and a liquid discharge head, an ultrasonic motor, and a dust removing device which use the piezoelectric element. An oriented piezoelectric ceramic includes as a main component a metal oxide represented by the following general formula (1), in which the oriented piezoelectric ceramic has a lead content and a potassium content that are each 1,000 ppm or less: (1−x)NaNbO3-xBaTiO3 . . . General formula (1), where a relationship of 0
