Abstract

A method produces a composite of a polymer and tungstic acid and/or molybdic acid; and the composite obtained by the method has high transparency and a desired refractive index. This composite contains tungstic acid and/or molybdic acid and a polymer that has a number average molecular weight of 1,000-10,000,000 and an ether bond and/or an ester bond. The content of tungstic acid and/or molybdic acid in the composite is 0.01-95% by weight.
