The light guide includes: plural light-emitting faces which are ring-shaped and formed concentrically in the other end in the tube axis direction of the light guide; and a non light-emitting face which is wall-like and formed along the tube axis direction of the light guide, at a border of adjacent ones of the light-emitting faces. |
