An endoscope for endotracheal intubation includes an elongated insertion section having a handle operation section, a bending operation mechanism and a bending mechanism for bending the insertion section, the bending mechanism including a long elastic member having one end positioned near the distal end portion of the insertion section and the other end fixedly coupled to the bending operation mechanism, a push-pull member having one end positioned near the distal end portion of the insertion section and the other end connected to the bending mechanism, a hollow member for coupling together distal end portions of the elastic member and the push-pull member so as to cause the portions to oppose each other along a bending direction, wherein the distal end portions of the elastic member and the push-pull member, which are coupled together with the hollow member, are provided integrally so as to provide a free end.
