PROBLEM TO BE SOLVED: To provide a high frequency treatment instrument for an endoscope, having excellent durability without the risk that an electrode wire tears an electrode tube in an axial direction even when a conductive operation wire is strongly pulled from a rear end side.SOLUTION: When a conductive operation wire 2 is pulled from a rear end side and the area of a rear end part of an electrode tube 3 is engaged with the area of a distal end part of a sheath tube 1, the rotation of the electrode tube 3 to the sheath tube 1 is regulated. Also, an electrode wire 4 is mechanically fixed to the vicinity of a base part of the electrode tube 3. |
