An endoscope for intubating an endotracheal tube includes an elongated insertion section having at least an image-transmitting fiber bundle and an illumination-light-transmitting fiber bundle, a handle operation section coupled to a proximal end of the insertion section, a bending operation mechanism provided in the handle operation section and a bending mechanism for bending the insertion section provided so as to extend from the inside of the insertion section to the bending operation mechanism, the bending mechanism including a long elastic member having one end positioned in the vicinity of 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 in the vicinity of the distal end portion of the insertion section and the other end connected to the bending mechanism, a hollow member for coupling together a distal end portion of the elastic member and a distal end portion of the push-pull member so as to cause the portions to oppose each other along a bending direction, wherein the distal end portion of the elastic member and the distal end portion of the push-pull member, which are coupled together with the hollow member, are provided integrally so as to provide a free end.
