PROBLEM TO BE SOLVED: To provide a small-sized and compact forcep plug of an endoscope in which a crack generated from a slit is not spread even when a treatment tool is repeatedly inserted and removed and the slit formed on the closing film of a lid body is firmly closed when not using the treatment tool.
SOLUTION: A bank-like part 30 projected from a position surrounding the slit 19 on the back side of the closing film 17 formed on the lid body 12 into a projected end entrance part 15 of a forcep plug main body 11 is formed. The inner peripheral wall surface 30i of the bank-like part 30 is formed in a circular shape in which the slit 19 is at a diameter position, and the outer peripheral wall surface 30o of the bank-like part 30 is formed in a roughly oblong shape in which the longitudinal direction of the slit 19 is a short axis.
