Abstract

See full text

An organic-inorganic composite material contains a cured material of an organic-inorganic composition containing a resin component, fine particles of a transparent conductive substance, and a polymerization initiator. Refractive properties of the Abbe number νd and anomalous dispersion θg, F of the organic-inorganic composite material are within a range surrounded by (νd, θg, F)=(16, 0.50), (16, 0.40), (23, 0.50), (23, 0.47). The content of the fine particles of the transparent conductive substance in the organic-inorganic composite material is from 7.7% to 20.0% by volume. The resin component contains a compound represented by the following formula:
