Estimating the term…
Into a mixture solution 2 of a high-refractive-index photo-curable resin A and a low-refractive-index photo-curable resin B, light capable of curing only the resin A is led through an optical fiber 1 so that a cured resin 211 of the resin A having a diameter substantially equal to the diameter of a core portion of the optical fiber is formed so as to extend from a tip of the optical fiber. Then, the residual mixture solution 2 is cured. In this manner, a module having the previously cured high-refractive-index resin 211 as an optical waveguide can be formed easily. On this occasion, the mixed state of the mixture solution 2 can be kept good enough to facilitate the formation of the high-refractive-index resin 211 when the solubility parameter δA of the high-refractive-index photo-curable resin A and the solubility parameter δB and volume fraction ΦB of the low-refractive-index photo-curable resin B satisfy the following expression (4). |δA−δB|<−7.5ΦB+6.0 (4)
A self-formable optical waveguide material composition containing a first photo-curable resin which can be cured by a certain wavelength, and a second photo-curable resin which is not cured by the certain wavelength but can be cured by another wavelength, wherein said self-formable optical waveguide material composition satisfies the expression (1):
