Abstract
An ultrasound treatment tool includes: an ultrasound blade including a treatment portion located at a distal end of the ultrasound blade, a jaw configured to open and close relative to the treatment portion. The jaw includes: a surface, a contact surface facing the ultrasound blade, the contact surface configured to be in contact with the treatment portion when the jaw is closed relative to the treatment portion. The contact surface comprises: a first resin layer positioned on the surface, the first resin layer formed of a first resin, a second resin layer layered over the first resin layer, the second resin layer formed of a mixed resin, the mixed resin being a mixture of a second resin and the first resin.
