Abstract
In a high-frequency knife, a through hole that extends in the direction of an axis is formed on a radial outer side of a second electrode in a larger-diameter portion, and a distance increasing portion increases a creeping distance along an external surface of the larger-diameter portion between an outer peripheral surface of the second electrode exposed to the outside and an opening of the through hole on a proximal end side.
