PROBLEM TO BE SOLVED: To provide a photoelectric composite substrate which has high adhesion between a polyimide film with metal wiring formed thereon and an optical waveguide. SOLUTION: This photoelectric composite substrate 1 contains a film-like optical waveguide 4 containing a core portion 8 and cladding layers 7, 9, and the polyimide film 5 with the metal wiring 6 formed on one side. The film-like optical waveguide 4 and the polyimide film 5 are laminated through an adhesive layer 3 so that the surface on which the metal wiring 6 of the polyimide film 5 is formed may face at least one outer surface of the film-like optical waveguide 4. The adhesive layer 3 includes (A) a polyimide silicone resin which has a specific structure, (B) a compound containing at least two oxiranyl groups, and (D) a cured radiation curable composition containing a cationic photopolymerization initiator.
