PROBLEM TO BE SOLVED: To provide a tip part of an ultrathin endoscope, capable of disposing a light guide fiber bundle without interference with other built-in objects and without reducing the number of optical fibers constituting the light guide fiber bundle for illumination, and without breaking the optical fibers because of the bending motion, etc. of a bending part.
SOLUTION: The distal end of a protection tube 13 is located on the way of the bending part 30, and the light guide fiber bundle 15 in the area 15C between the location and the rear end of a distal end body 2 or 14 is not coated with tubes, etc. The light guide fiber bundle 15 is molded in a certain flexible shape by filling the space among optical fibers with a flexible low-viscosity adhesive with elasticity.
