Provided is an optical material which has a high transmittance, a high refractive index, a low Abbe constant, a high secondary dispersion property, and a low water absorption rate. The optical material includes a polymer of a mixture which contains: a sulfur-containing compound represented by the following general formula (1): a sulfur-containing compound represented by the following general formula (2): and an energy polymerization initiator, in which a content of the sulfur-containing compound represented by the chemical formula-2 is 10% by weight or more to 60% by weight or less, an Abbe constant (&ngr;d) of the polymer of the mixture satisfies 18<&ngr;d<23, and a secondary dispersion property (&thetas;g,F) thereof satisfies 0.68<&thetas;g,F<0.69.
