ABSTRACT:
An endoscope includes an insertion portion and a treatment instrument insertion channel, and is inserted into a body cavity; an operation portion which is connected to a proximal end side of the insertion portion; and a treatment instrument raiser which has a guiding surface for guiding a treatment instrument, and able to rise according to an operation from the operation portion. The raiser includes a slit which is formed on a distal end side of the guiding surface and with which a guide wire guided toward the distal end side opening can be engaged, and a guide wire guiding unit which is formed on an outer periphery of the guiding surface and serves to guide the guide wire into the slit. The guide wire is guided into the slit by the guiding unit, when the raiser is raised by the operation from the operation portion.
