PROBLEM TO BE SOLVED: To provide a vibrating wave actuator which enables time saving of time and trouble required for machining during manufacture of a stator. SOLUTION: The circumferential edge of a supporting member 19 is connected to the inner circumferential surface of an elastic member 16 with a piezoelectric element joined on its underside at the end on the underside in the direction of the thickness of the elastic member 16. The thickness of the elastic member 16 is larger than the thickness of the supporting member 19 on the side of the circumference of the elastic member 16, and the thickness of the elastic member 16 is equal to the thickness of the supporting member 19 on the side of the inner circumference of the elastic member 16. A slope 20 is formed at the surface of the elastic member 16 on the side of the inner circumference of the elastic member 16, and thickness of the elastic member 16 is gradually reduced as it goes toward the side of the inner circumference. Accordingly, the underside of the elastic member 16 is connected to the underside of the supporting member 19 without steps, and the surface of the elastic member 16 is connected to the surface of the supporting member 19 without steps as well. |
