Abstract: An endoscope includes a standing base in a tip portion body, an operation wire of which a tip side is connected to the standing base, and a stretchable coating member that covers the operation wire along an extending direction of the operation wire and so as to allow the operation wire to be relatively movable over the entire region from a connection portion between the standing base and the operation wire to an operation wire-guide passage. A tip of the coating member and the standing base are liquid-tightly fixed to each other, and a base end of the coating member and the operation wire-guide passage are liquid-tightly fixed to each other, and the coating member is disposed at a position where a moving path of the coating member and a moving path of a treatment tool led from a treatment tool-guide passage do not interfere with each other.
