Abstract:
1. An optical waveguide forming resin composition, comprising: (A) a liquid oxetane compound; (B) a liquid epoxy compound; (C) an alkylene glycol; and (D) a photoacid generator, wherein the optical waveguide forming resin composition is free from a solid resin component and the viscosity thereof under a 25° C. environment is within the range of 10 to 20 mPa·s, and wherein the proportion of the liquid oxetane compound (A) is 70 wt % or more, the proportion of the liquid epoxy compound (B) is 20 wt % or less, the proportion of the alkylene glycol (C) is 20 wt % or less, and the proportion of (B)+(C) is 30 wt % or less based on an overall amount of resin components of the optical waveguide forming resin composition.
