PROBLEM TO BE SOLVED: To provide an oscillator capable of preventing peeling-off even if load is applied in a polishing process by increasing adhesive strength with an increase in an adhesive area to a friction member having high friction coefficient, thus eliminating the peeling-off of the friction member even when an increase in pressurizing/output torque by use of the friction member. SOLUTION: This oscillator includes an elastic body 1, a piezoelectric element 2 jointed to the one face of the elastic body 1, and the friction member 4 fixed to the other face of the elastic body 1 and is formed into a comb-toothed shape by dividing the opposite side to the joint side of the piezoelectric element 2 in the diametrical direction. The elastic body 1 is formed with a recessed section for fitting-in the friction member 4, and the friction member 4 is fixed in the recessed section with adhesives, using at least two surfaces or one curved surface. |
