Abstract: A vibration transmitter includes: a first rod including a fitting hole extending along the longitudinal axis thereof; and a second rod attached to a distal end portion of the first rod by a fitting portion fitted into the fitting hole in a state where a compressed surface pressure is received from the inner surface of fitting hole. The first rod includes: a first region in which the fitting portion is fitted into the fitting hole; and a second region positioned proximal of the first region. In the first region of the first rod, a crystal grain diameter is larger than that in the second region of the first rod.
