Patent ID: 8847486

Claim:
A resin material comprising: a main material having a vinyl group (—CH═CH 2 ); and a sub-material having a plurality of silane groups (Si—H); and a catalyst that promotes binding between the vinyl groups and the silane groups, wherein a content of the plurality of silane groups is within 0.7 to 0.9 times a content of the vinyl group, wherein an optical density (absorbance) of a Fourier transform infrared spectroscopy (FT-IR) signal for silane groups (Si—H) not reacted with the vinyl groups (—CH═CH 2 ) is in the range of 0.0002 to 0.004 (arb. unit) in a first wavenumber range, and the optical density is in the range of 0.005 to 0.01 (arb unit) in a second wavenumber range different from the first wavenumber range, wherein the first wavenumber range is in the range of 2100 to 2200 cm −1 , and wherein the second wavenumber range is in the range of 870 to 930 cm −1 .
