摘要：
The invention relates to an ultrasonic motor, an electronic timepiece, and an electronic apparatus, which includes an ultrasonic rotor formed from a base resin of thermoplastic resin. Moreover, the invention includes an ultrasonic rotor which contacts with an ultrasonic stator under pressure, the ultrasonic rotor being formed from a filler containing resin. Alternatively an electronic timepiece with the ultrasonic motor is constructed. Furthermore, an electronic apparatus with the ultrasonic motor which is constructed.
