PROBLEM TO BE SOLVED: To exhibit the coagulating action of an organismic tissue by restraining the separation of a high frequency current into the organismic tissue through a perfusate in an electrode knife operation using the perfusate of electrolyte. SOLUTION: In this electrode, a projecting tip electrode part 3 is integrally and coaxially formed on a tip surface of a bar-shaped heat absorbing body part 2, and a pipe-shaped output conducting metallic part 5 and a joining part 6 being a conductive terminal are connected in order to a rear end part of the heat absorbing body part 2, and are constituted so as to cover a surface except for the tip electrode part 3 and the joining part 6 with an insulating coating film 7. When the tip electrode part 3 is sunk in the affected part, the affected part is obstructed by the action of a step part 4 formed of the tip electrode part 3 and the heat absorbing body part 2. Therefore, infiltration of a perfusate into the affected part is prevented, and the separation of a high frequency current by contact of the tip electrode part 3 with the perfusate can be restrained. |
