Abstract: The endoscope of the invention includes: an insertion portion; a multi-lumen tube including bending operation wire insertion holes; bending operation wires inserted into the bending operation wire insertion holes; a wire retaining member including two opening portions; a pressing member that presses a distal end surface of the multi-lumen tube through the wire retaining member; a treatment instrument insertion channel; a distal end rigid member including a through hole; and a pipe member. A contact area of the wire retaining member with a distal end surface of the multi-lumen tube is set to be larger than a contact area of a pressing member with the wire retaining member. The pressing member is disposed between the two opening portions of the wire retaining member. The wire retaining member includes a pipe holding portion that holds the pipe member and is held between the distal end rigid member and the multi-lumen tube.
