摘要: The present invention relates to a flexible optical waveguide prepared by using resin film for forming an at least one of lower cladding layer, core layer and upper wherein ten point average roughness (Rz) on surface either the is 0.5 μm or more 10 less, production process same module waveguide. Provided are which excellent in adhesive property compounding with electric printed wiring board turning into multilayer,
