摘要：

PROBLEM TO BE SOLVED: To provide a high-frequency treatment instrument for an endoscope, capable of easily performing a process of releasing a swelling region on the surface of the mucous membrane while endoscopically cauterizing and incising the swelling region etc. with high-frequency waves, and also a process of resecting the swelling region at once.

SOLUTION: A conductive line 8 is bent backward at both ends of an area along the most distal end face 2a of a distal end sheath 2, and is loosely inserted into a proximal side sheath 1 from the distal end sheath 2 via a pair of through-holes 6 formed on a side wall in the vicinity of the distal end of the distal end sheath 2. By operating the conductive line 8 forward/backward in the axial direction from the proximal end side, a high-frequency electrode 7 can be made to project forward from the distal end of the distal end sheath 2. By rotationally operating the conductive line 8 around the axis from the proximal end side, the distal end sheath 2 is rotated around the axis relative to the proximal end sheath 1 so that the direction of the most distal end face 2a of the distal end sheath 2 can be changed.
