Abstract:
1. A film-shaped optical waveguide production method for producing a plurality of film-shaped optical waveguides, the method comprising the steps of: defining a plurality of film-shaped optical waveguide formation regions on a substrate; producing the film-shaped optical waveguides in the respective film-shaped optical waveguide formation regions by forming under-cladding layers in the respective film-shaped optical waveguide formation regions by forming a photosensitive resin layer on a generally entire surface of the substrate, selectively exposing portions of the photosensitive resin layer present in the respective film-shaped optical waveguide formation regions and defining the exposed portions of the photosensitive resin layer as the under-cladding layers, and forming cores on the respective under-cladding layers; and separating the produced film-shaped optical waveguides from the substrate without cutting the substrate.
