The high-frequency treatment instrument 1 is a high-frequency treatment instrument for performing a high-frequency treatment on a pathological lesion portion (subject tissue) not shown and includes a sheath (elongated extension member) 2, a treatment electrode 5 which is rotatably disposed at a distal end of the sheath and which extends in a direction substantially parallel to a diameter direction of the rotation, an operating wire (axial member) 6 for allowing the treatment electrode to rotate around the distal end of the sheath, and an operating portion 7 to which proximal ends of the sheath 2 and the operating wire 6 are connected. According to a high-frequency treatment instrument, by enabling a treatment on a subject tissue without using a curving operation of an endoscope it is possible to facilitate a procedure.
