An object of the present invention is to provide an endoscope that can reliably protect incorporated components in a bending portion of an insertion portion of the endoscope without impairing ease of assembly, and in order to achieve the object, an endoscope according to the present invention includes: a bending tube 24 including ring-like members 25c pivotally joined via a pair of pivots 25a facing each other or a pair of pivots 25b facing each other, the pair of pivots 25a and the pair of pivots 25b being disposed in an up/down direction or a left/right direction relative to a center axis Ax, the bending tube 24 being bendable in an arbitrary direction a pair of first pull wire guides 27 provided between adjacent pivots so as to project inward of a ring-like member a forceps channel 13 disposed so as to be contactable with the pair of first pull wire guides and a pair of second pull wire guides 26 positioned at respective positions, in the ring-like member, at which the pair of second pull wire guides 26 substantially faces the pair of first pull wire guides, the pair of second pull wire guides 26 being provided so as to project inward of the ring-like member and being disposed so that a distance D1 between distal end portions extending toward an inner circumferential side of the ring-like member is a distance that is smaller than an outer diameter D2 of the forceps channel.
