PROBLEM TO BE SOLVED: To form a high polymer optical waveguide pattern capable of being easily massproduced and easily connected to optical parts by having the easy pattern formability, and using a specific organic oligmer superior in heat resistance and moisture resistance, having low double refraction, and superior in workability. SOLUTION: In a photosensitive composition for an optical waveguide, including an organic oligomer and a polymerization starting agent, the organic oligomer is silicone oligomer presented by a formula, and the like. In the formula, X is a hydrogen atom, a heavy hydrogen atom, a halogen atom, an alkyl group or an alkoxy group, (m) is an integer of 1-5, and (x) and (y) are respectively ratio of units, and are not 0. R1 is a methyl group, an ethyl group or an isopropyl group. An epoxy oligomer or an acryl oligomer can be also used as the organic oligomer, besides this silicone oligomer. |
