Abstract: PROBLEM TO BE SOLVED: To provide a resin composition having excellent mechanical strength such as rigidity or impact resistance, surface hardness, thermal stability and transparency and suitably used as practical organic glass, etc., such as window glass. SOLUTION: The resin composition is obtained as follows. A surface layer having epoxy groups is formed on the surface of inorganic oxide fine particles having ≤380 nm average primary particle diameter and the resultant inorganic oxide fine particles are then compounded in a monomer of a polycarbonate resin to form a polymerization reaction solution. The polycarbonate resin is synthesized from the polymerization reaction solution by a transesterification method. Thereby, the resin composition in which the inorganic oxide fine particles are bound through the surface layer to the polycarbonate resin with covalent bonds and dispersed in the polycarbonate resin is produced.
