Abstract
A photosensitive epoxy resin composition for formation of an optical waveguide is provided, which contains an epoxy resin component, and a photo-cationic polymerization initiator, wherein the epoxy resin component includes a solid semi-aliphatic bifunctional epoxy resin. The optical waveguide formation photosensitive epoxy resin composition is usable as an optical waveguide forming material having higher R-to-R (roll-to-roll) adaptability (lower tackiness and uncured-state flexibility), a lower refractive index, excellent patternability, and excellent laser processability mirror forming processability).
