ABSTRACT:
An endoscope comprises an insertion section and a light guide contained in the internal space of the insertion section and adapted to guide an illumination light. The light guide includes a number of elongated optical fibers having individual distal end portions, which are bound into a bundle and bonded together. At least one spacing member is contained in the distal end portion of the bundle of optical fibers, with the optical fibers kept loose on the proximal-end side of the distal end portion of the optical fiber bundle to provide gaps among the optical fibers.
