An optical material is constituted by a resin material and inorganic fine particles dispersed in the resin material. The inorganic fine particles include SiO2, and at least a part of the surface of the SiO2 is SiON wherein an oxygen atom is substituted by a nitrogen atom. The optical material can be freely controlled in a wide range of optical constants and has, in particular, negative abnormal dispersion that cannot be created by optical glass while maintaining high transmittance. Provided are the optical material, an optical element constituted by the optical material, and a composite optical element including the optical element. |
