<P>PROBLEM TO BE SOLVED: To provide a method of manufacturing an optical waveguide for touch panel such that size change due to heat is small and formation positions of a clad layer and a core of an optical waveguide on a base material are accurate even when including a step of continuously applying and heat-treating the clad layer or core. <P>SOLUTION: The method of manufacturing the optical waveguide for touch panel includes a step of selecting a long base material made of stainless steel and continuously applying a photosensitive resin composition (1') for clad layer formation onto a base material 10; a first preheating step of heating the resin composition so as to volatilize a solvent in the composition; a step of irradiating the resin composition with an irradiation beam L to form a clad layer 1; a step of continuously applying a photosensitive resin composition for core formation onto the clad layer; a second preheating step of heating the resin composition so as to volatilize a solvent in the composition; and a step of irradiating the resin composition with an irradiation beam through a photomask to expose and cure the resin composition, and then dissolving an unexposed part away using a developer so as to form the core in a pattern shape. <P>COPYRIGHT: (C)2012,JPO&INPIT |
