PROBLEM TO BE SOLVED: To provide an optical waveguide capable of effectively coupling outgoing light from a light source, a method for manufacturing this optical waveguide easily at a low cost with high productivity, and to provide an optical information processor using this optical waveguide. SOLUTION: The optical waveguide 1 consists of a cemented body of a clad layer 2 and a core layer 4, and is constituted so that the light is made incident to the core layer 4 through the clad layer 2, and a light condensing means 7 is formed integrally with the clad layer 2 at a position corresponding to a light incident part 5 to the core layer 4. The method for manufacturing the optical waveguide 1 includes a process for molding the light condensing means 7 integrally with the clad layer 2 at the position corresponding to the light incident part 5 to the core layer 5, and a process for cementing the clad layer 2 to the core layer 4 on the surface opposite to the light condensing means 7. The optical information processor has: the optical waveguide 1 of this invention; a light incident means 81 for making the light incident to the core layer 4 of the optical waveguide 1; and a light receiving means 91 for receiving the outgoing light from the core layer 4.
