Abstract
An endoscope comprises an elongated insertable part, illumination device for illuminating an object to be imaged, and observing device for allowing observation of the object to imaged upon receiving a light from the object incident from an observing window disposed at a tip portion of the insertable part, the insertable part being provided with an inner tube and a tubular outer cover for covering the outer periphery of the inner tube. The outer cover is fixed to the inner tube by means of a cylindrical fixing member externally fitted to the outer cover. Further, a cylindrically projecting member for radially expanding the outer cover is provided in the vicinity of and on the outside of at least one axially opposite end portion of the fixing member in such a manner that an outside diameter of the outer cover in the vicinity of and on the outside of the axially opposite end portion of the fixing member becomes substantially equivalent to that of the fixing member.
