Abstract
A material for an optical component comprising polytungstic acid having peroxo groups, and an optical component, at least part of which is constituted of a thin film of the above-mentioned material. By using this material, a thin film of an inorganic material having an excellent stability is formed by the inexpensive wet painting method. An optical component using the above-mentioned thin film can be formed on an arbitrary substrate with high accuracy at a low temperature of about 100.degree. C. or below. The polytungstic acid may contain carbon as a heteroatom and/or may have Nb, Ti, V, Ta and/or Mo substituted for part of W.
