PROBLEM TO BE SOLVED: To provide a user-friendly high-frequency treatment tool for an endoscope, allowing free high-frequency incision treatment and high-frequency exfoliation treatment to mucosa with one treatment tool.SOLUTION: In a high-frequency treatment tool for an endoscope configured such that an electrode wire 4 is exposed outside an electrode tube 3 between a pair of electrode passage holes 5, 5 formed in the side face of the electrode tube 3 at an interval in the axial direction, a projection 6 projecting in the radial direction is formed in an edge part of a distal end portion of the electrode tube 3 and in a region on both sides sandwiching at least a front position of the electrode wire 4 in the circumferential direction.COPYRIGHT: (C)2014,JPO&INPIT【課題】粘膜に対する高周波切開処置と高周波剥離処置を一つの処置具で自在に行うことができる使い勝手のよい内視鏡用高周波処置具を提供すること【解決手段】電極チューブ3の側面に軸線方向に間隔をあけて形成された一対の電極通過孔5,5間において電極ワイヤ4が電極チューブ3外に露出するように構成された内視鏡用高周波処置具において、電極チューブ3の最先端部分の縁部であって少なくとも電極ワイヤ4の前方位置を周方向に挟む両側の領域に、径方向に突出する突起6を形成した。【選択図】 図3
