摘要：Provided are an organic-inorganic composite resin composition and an organic-
inorganic composite resin material made of a cured product thereof, containing at leastan organic compound having a polymerizable functional group, metal oxide fine particles,and a polymerization initiator. The cured product obtained by curing the organic-inorganic composite resin composition through application of an active energy has arefractive index nd of 1.61 or more and 1.65 or less, Abbe's number νd of 13 or more and20 or less, and an anomalous dispersion characteristic θg, F of 0.42 or more and 0.54 orless. Further provided is an optical element comprising a transparent substrate and theorganic-inorganic composite resin material formed on the transparent substrate.
