A film of a polymer obtained by ultraviolet curing a photosensitive substance (A, D), which has a reactive oligomer containing at least one epoxy ring as one of components, and which has a viscosity adjusted to 500 cps to 10,000 cps, is used as a core (9, 17) or a cladding (5, 10, 13, 18). By this measure, an optical waveguide satisfying both of a low price and high performance, and a method for producing the same are provided. <IMAGE> |
