Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an injector capable of efficiently releasing the adhesion of a stator and a rotor of an ultrasonic motor.SOLUTION: The injector 1 for injecting a chemical liquid includes: an ultrasonic motor unit 3 with the ultrasonic motor 31; a drive mechanism 4 to be driven by the ultrasonic motor unit 3 so as to feed the chemical liquid when the ultrasonic motor 31 rotates forward; and a control device 5 for controlling the ultrasonic motor 31 of the ultrasonic motor unit 3. The ultrasonic motor 31 has the stator 32 and the rotor 33. The control device 5 controls the ultrasonic motor 31 to alternately repeat forward rotation and backward rotation so that the adhesion of the stator 32 and the rotor 33 is released.
