PROBLEM TO BE SOLVED: To improve cutting efficiency by ultrasonic oscillation by substantially effective projections/recesses on the surface of a rough face part at a treating part by forming the rough surface part on the external surface of a probe and making intervals between its projecting and recessed parts at least 100μm and not longer than the two-fold of a maximum amplitude. SOLUTION: In the ultrasonic treating tool for treating to a living tissue by ultrasonic oscillation, projection/recess parts are formed on the outer surface of a probe 3 for treating the living tissue and intervals between mountain parts 7 being these projection/recess parts are at least 100μm and not longer than the two-fold of the maximum amplitude of the ultrasonic oscillation at the prove. A projecting and recessed rough face part 5 is formed on the outer surface of the probe 3 and active operation by its mountain part 7 and a range the operation of the mountain part 7 are made substantially within the oscillation width of ultrasonic oscillation to improve treating efficiency by ultrasonic oscillation. |
