摘要： Provided is an ultrasonic motor including an annular vibrator and an annular moving member that is brought into pressure-contact with the vibrator. The vibrator includes an annular vibrating plate and an annular piezoelectric element. The piezoelectric element includes an annular lead-free piezoelectric ceramic piece, a common electrode arranged on one surface of the piezoelectric ceramic piece, and a plurality of electrodes arranged on the other surface of the piezoelectric ceramic piece. The plurality of electrodes include two drive phase electrodes, one or more non-drive phase electrodes, and one or more detection phase electrodes. A second surface of the vibrating plate includes a plurality of groove regions extending radially, and the depths of the groove regions change in a circumferential direction along a curve obtained by superimposing one or more sine waves on one another. The ultrasonic motor exhibits a sufficient drive speed while suppressing generation of an unnecessary vibration wave.
