ABSTRACT:
An illuminating apparatus of an endoscope having a bulb disposed to face an entrance end surface of a light guide for illumination to supply illuminating light to the light guide. A concave mirror surrounds side and rear portions of the bulb to converge light emitted peripherally from the bulb in the vicinity of the entrance end surface of the light guide. A convex lens is formed at the distal end of the bulb to allow light emitted forwardly and obliquely forward from the bulb to be incident on the entrance end surface of the light guide.
