As for endoscope disposal tool, as it has with the electrode section which is provided in the point of the sheath and the sheath which possess electric insulated as for the electrode section, extending facilities it is done in axis direction of the sheath, extending from the point of the sheath, in order in a state where it is exposed outside to extend to axis direction in the electrode and the basic end face of the arrangement possible cylinder shape, to be locked when the point of the electrode has been inserted in the concave section which is provided, to possess the major diameter which is larger than major diameter of the electrode, to possess with the advanced tip/chip 22 which was formed with the single electric insulated material, in the concave section, the point of the electrodeInsertion possibility, at the same time, the small diameter section which possesses the inside diameter which is smaller than inside diameter of the concave section is formed the section, with the concave section and the electrode, at the same time, on advanced side than the small diameter section, the person in charge stopping possible filling up component is provided in the small diameter section.内視鏡処置具は、電気絶縁性を有するシースと、シースの先端部に設けられた電極部とを備え、電極部は、シースの軸線方向に延設されるとともに、シースの先端部から突出して外部に露出した状態に配置可能な棒状の電極と、基端面に軸線方向に延びるように設けられた凹部に電極の先端部が挿入された状態で固定され、電極の外径よりも大きい外径を有し、単一の電気絶縁性の材料で形成された先端チップ22とを有し、凹部には、電極の先端部を挿入可能、かつ、凹部の内径よりも小さい内径を有する小径部が形成され、凹部と電極との間で、かつ、小径部よりも先端側には、小径部に係止可能な充填部材が設けられている。
