The purpose of the present invention is to provide an endoscope capable of preventing a multi-lumen tube from deforming due to a pulling force applied by a bending operation wire. To this end, this endoscope is provided with: an insertion part having a bending section; a multi-lumen tube (22) having a bending operation wire insertion hole (22c) extending therethrough in the longitudinal axis direction; a bending operation wire (27) inserted through the bending operation wire insertion hole; a wire securing member (25) that is in contact with the distal end surface of the multi-lumen tube and has an opening (25c) from which the bending operation wire is withdrawn; and a pressing member (26) that has a fixed part (26a) fixed to the bending operation wire and a contact part (26b) in contact with the wire securing member, and that presses the distal end surface of the multi-lumen tube via the wire securing member when the bending operation wire is pulled. The area (D1) of contact between the wire securing member and the distal end surface of the multi-lumen tube is set to be greater than the area (D2) of contact between the contact part and the wire securing member.L'objectif de la présente invention est de fournir un endoscope capable d'empêcher un tube à lumières multiples de se déformer en raison d'une force de traction appliquée par un fil d'opération de flexion. A cet effet, l'endoscope comprend : une partie d'insertion ayant une section de flexion; un tube à lumières multiples (22) ayant un trou d'insertion de fil d'opération de flexion (22c) s'étendant à travers celui-ci dans la direction de l'axe longitudinal; un fil d'opération de flexion (27) inséré à travers le trou d'insertion de fil d'opération de flexion; un élément de fixation de fil (25) qui est en contact avec la surface d'extrémité distale du tube à lumières multiples et a une ouverture (25c) à partir duquel le fil d'opération de flexion est retiré; et un élément de pression (26) qui a une partie fixe
