PROBLEM TO BE SOLVED: To obtain a transparent composition having excellent transparency and high refractive index capable of obtaining a transparent composition having excellent optical properties, and having high refractive index having excellent dispersibility, and a resin composition and a resin using the same. A molded article, film or coating agent comprising the composition is provided. SOLUTION: The inorganic fine particles (A) are inorganic fine particles characterized in that the surface is modified with an organic substance (B) and a transparent composition (D) is obtained when dispersed in a transparent polymer (C). (A) to (C) are oxides containing (A) one or more inorganic substances selected from titanium, zirconium, zinc and aluminum, and inorganic fine particles having a particle diameter of 1 to 50 nm, (B) Polymer (c) in which the organic substance forms a main skeleton by living radical polymerization starting from the modified molecule (a) having a molecular weight of less than 1000 and the initiator (b) introduced on the surface of the inorganic fine particles And (C) inorganic fine particles in which the transparent polymer is an optical transparent polymer.
