    Abstract: Disclosed is a resin material for optical purposes, which has high light permeability and high refractive index stability against temperature variation. Also disclosed is an optical element utilizing the resin material. The resin material for optical purposes comprises a curable resin and an inorganic microparticle comprising two or more metal oxides having different refractive indexes and dispersed in the curable resin, wherein the inorganic microparticle has a refractive index distribution, has the surface treated with a surface-treating agent, and is at least partially modified with a surface-modifying agent having a polymerizable functional group, and wherein the refractive index of the curable resin after being cured (nh) and the refractive index of the inorganic microparticle (ng) meet the requirement represented by the formula (1).
