<P>PROBLEM TO BE SOLVED: To provide a light guide having uniform quality, which can converge outgoing light from a light-emitting end face and can irradiate a target irradiation part with it, by merely integrating a plurality of coated optical fibers in parallel as they are and polishing them. Ž<P>SOLUTION: The light guide is composed of bundled fibers 13 for which a plurality of coated optical fibers 12 are arrayed in parallel and bundled circularly, wherein the light-emitting end face 16 is formed by a non-planar part 16a inclined outward from the center side. The proximity to the center of the light-emitting end face 16 may be made a planar shape 16b, and the light-emitting end face can be made convex in the outgoing direction of light. Further, the non-planar part 16a of the light-emitting end face can be formed by polishing. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
