PROBLEM TO BE SOLVED: To provide a resin composition having improved dispersibility of an inorganic ultraviolet absorber in a transparent thermoplastic resin and suppressed photocatalytic activity and metallic ion releasing property of the ultraviolet absorber and provide a molded article of the resin composition. SOLUTION: The resin composition is produced by dispersing an inorganic ultraviolet absorber such as titanium oxide and zinc oxide in a transparent thermoplastic resin. The ultraviolet absorber is treated with a surface treating agent selected from silane coupling agents, titanium coupling agents, etc., having an alkoxy group or hydroxy group and an organic functional group. The compounding ratio X of the surface treating agent to the ultraviolet absorber satisfies the formula 0.05<X<10, and the content of the ultraviolet absorber in the transparent thermoplastic resin is >0.01 wt.% and <30 wt.%.
