摘要： A high-frequency treatment tool for an endoscope, having an electrically insulating flexible tube, an operating wire, a high-frequency electrode, which is provided at a distal end of the operating wire and configured to be protrusible and retractable from a distal end of the flexible tube in the axial direction of the flexible tube, and a tubular member, is provided. The tubular member is fitted on the operation wire and immovably attached thereon by plastic deformation, which is caused as at least a part of the tubular member is deformed to interfere with an inner circumferential surface of the flexible tube so that the operating wire is halted with respect to the flexible tube at an arbitrary position in the flexible tube by frictional resistance caused between an interfering part of the tubular member and the inner circumferential surface of the flexible tube.
