Abstract
Provided is a method of manufacturing a vibration transmission member for an ultrasonic treatment tool. The method includes: applying a release agent between a surface of a vibration transmission member configured to transmit ultrasonic vibration and a die for hot forging; performing hot forging to form the vibration transmission member after the applying of the release agent; removing, after the performing of the hot forging, a part of an oxide film formed in the performing of the hot forging by a first surface treatment; performing pickling to remove the oxide film after the removing of the part of the oxide film by a blasting treatment; and performing coating with a resin after the performing of the pickling.

A method of manufacturing a vibration transmission member for an ultrasonic treatment tool, the method comprising, in order:
- applying a release agent between a surface of a base material and a die for hot forging;
- performing hot forging on the base material applied with the release agent to form the vibration transmission member, the vibration transmission member being configured to transmit ultrasonic vibration;
- performing a first surface treatment, thereby removing a part of an oxide film formed on a surface of the vibration transmission member in the performing of the hot forging;
- performing pickling to remove at least a part of a remainder of the oxide film that was not removed in the first surface treatment;
- coating at least part of the surface of the vibration transmission member with a resin;
- and
- performing a second surface treatment after the performing of the pickling and before the coating,
- wherein:
- the first surface treatment is a blasting treatment using a first projection material,
- the second surface treatment is a blasting treatment using a second projection material, and
- a diameter of the second projection material is larger than a diameter of the first projection material.
