PROBLEM TO BE SOLVED: To provide a high frequency snare for endoscope capable of cutting a polyp, etc., without bleeding, without a possibility of mechanically cutting the polyp erroneously by tightly binding it and without making a burn on the wide range of the human tissue by a high frequency current conduction. SOLUTION: A twisted wire consisting of a conductive strand 11a made of a conductive material and a low conductive strand 11b whose surface at least is made of an electrical insulating material or high impedance material is used as an elastic wire 11 forming the snare loop 10.
