Abstract:
The present invention relates to a dry film for an optical waveguide which has a carrier base material, a resin layer for an optical waveguide that can be cured by active energy ray or heat, and a protective film. The surface of the protective film that is in contact with the resin layer for an optical waveguide is a roughened surface.
