Flexible optical waveguide device and process for the production thereof
First Claim
1. A flexible optical waveguide device obtained by forming a refractive index distribution in a light-permeable polymer film to obtain an optical wave-guide film and forming a cured resin layer on at least one surface of the optical wave-guide film, the cured resin layer(s) comprising, as main components, a polyamide resin, and at least one member selected from the group consisting of an epoxy resin and a phenolic resin.
