And a fixing means for fixing to. Further, the loop-shaped portion of the tip of the snare wire inserted through the endoscope hood and the channel of the endoscope is inserted through the slit of the endoscope hood and pulled out to be wrapped around the outer periphery of the endoscope hood. A high-frequency treatment device is configured with the high-frequency snare wire hooked in the closed state. Also, a first step of attaching the endoscope hood to the endoscope tip portion, a second step of protruding the tip of the high frequency snare from the endoscope tip surface, and a loop of the snare wire tip of the high frequency snare.
