<P>PROBLEM TO BE SOLVED: To provide a resin composition for an optical waveguide, which has superior adhesion to a clad layer, can reduce a loss in an optical waveguide, and has high patterning property in forming a core, and to provide an optical waveguide using the same. <P>SOLUTION: A resin composition for an optical waveguide contains a partially-acrylated multifunctional epoxy resin (A) having an epoxy group and a (meta)acrylate group in the same main chain as a main component and a photopolymerization initiator (B) as a component for curing the resin (A). In an optical waveguide composed of a substrate, a clad layer formed on the substrate, and a core part for transmitting an optical signal formed on the clad layer, the core part is made of the resin composition for an optical waveguide. <P>COPYRIGHT: (C)2012,JPO&INPIT |
