摘要

A lens (11) is bowl-shaped. The inner surface (11N) of the bowl shape is a containing recess (11N) which serves as a light receiving surface, and the outer surface (11S) of the bowl shape is a lens surface (11S) which serves as a light emitting surface. The inner surface (11N) of the bowl shape is tapered toward the bottom of the bowl-shaped lens (11), and a conical, tip recess (12) which is recessed from the outer surface (11S) is formed at the tapered end which is the bottom of the bowl-shaped lens (11).
