PROBLEM TO BE SOLVED: To provide a method for manufacturing an opto-electric hybrid board which improves the alignment accuracy of an optical element with respect to a core of an optical waveguide. SOLUTION: When a core 7 of an optical waveguide W is formed on a surface of an electric circuit board E, the core 7 and optical element positioning alignment marks A are simultaneously formed from a photosensitive resin layer including a core 7 formation region and an alignment mark A formation region by a single photolithography process. In an optical element mounting step, a light emitting element 11 and a light receiving element 12 are mounted at proper positions with respect to the core 7 of the optical waveguide W with reference to the alignment marks A.
