The present invention provides an endoscope capable of more reliably observing bending of the large intestine. An endoscope according to an embodiment of the present invention includes a distal end portion provided with an imaging device having a fisheye lens, a bending portion, an insertion portion and an operation portion connected to the distal end portion and composed of a plurality of bending tools. The insertion portion is a portion connecting the bending portion and the operation portion, and at least a part of the insertion portion is inserted into the body cavity or taken out from the body cavity, thereby moving the distal end portion and the bending portion into the body cavity, Has a protruding portion which protrudes forward and decreases in width as going forward, and the photographing device is provided at the most distal end of the projecting portion.本発明は、大腸の屈曲をさらに確実に観察できる内視鏡を提供する。本発明の一実施例による内視鏡は、魚眼レンズを備えた撮影装置が設けられる先端部、前記先端部に連結されて複数の湾曲具からなる湾曲部、挿入部及び操作部を備える。挿入部は、湾曲部と操作部を連結する部分であって挿入部の少なくとも一部が体腔内に挿入されたり体腔から取り出されることにより先端部及び湾曲部を体腔内に移動させて前記先端部は前方に向かって突出し前方に行くほど幅が減少する突出部を備え、前記突出部の最先端に前記撮影装置が設けられる。
