摘要:
A method of manufacturing an optical waveguide for a touch panel is provided which achieves a small dimensional change due to heat to provide precise formation positions of a cladding layer and cores on a substrate. The method includes: selecting an elongated substrate made of stainless steel to continuously apply a first photosensitive resin composition; heating the first photosensitive resin composition to volatilize a solvent therein; irradiating the first photosensitive resin composition to form the cladding layer; continuously applying a second photosensitive resin composition; heating the second photosensitive resin composition to volatilize a solvent therein; and irradiating the second photosensitive resin composition with irradiation light through a photomask to expose the second photosensitive resin composition to the irradiation light, and thereafter dissolving away unexposed portions of the second photosensitive resin composition by using a developing solution.
