Abstract

An endoscope tip part has impact resistance even when applied to a thin endoscope, and the light distribution characteristics thereof can be improved even at a wide angle of view. An endoscope tip part includes a tip part main body that is attached to the tip of an insertion section of an endoscope and a positive-power transparent-plastic tip lens that is integrated with the tip part main body through two-color molding. The tip lens is a lens that is located closest to an object, among optical elements constituting an illumination optical system of the endoscope, and the tip part main body is provided with an insertion hole into which two positive-power rear lenses that will be disposed behind the tip lens are inserted.
