PROBLEM TO BE SOLVED: To provide an optical-path-conversion optical waveguide that can form a reflection area in an optical waveguide by simple machining. SOLUTION: An optical incident/exit hole 14 of a conical or a semispherical shape is formed from the surface of the optical waveguide 10 into the core 12 by means of a machining drill 15, with a reflection film 16 formed on one side of the optical incident/exit hole 14, and also with resin 17 filled therein.
