Abstract: PROBLEM TO BE SOLVED: To provide a mucosal resection instrument for an endoscope capable of preventing unexpected disengagement of a loop from a cap even if the cap is deformed when inserted into a body cavity or during the treatment inside the body cavity. SOLUTION: The mucosal resection instrument for the endoscope has a lock piece 13 near a pawl part 7 formed at the top edge of the cap 2. The lock piece 13 presses a snare wire 22 disposed along the pawl part 7 and the snare wire 22 is held by both the pawl part 7 and the lock piece 13. In this way, the snare wire 22 of a high frequency snare is hardly disengaged unexpectedly when the snare wire is inserted into the body cavity or during the treatment inside the body cavity in performing the endoscopic mucosal resection.
