PROBLEM TO BE SOLVED: To provide a resin composition which keeps high transparency, and has excellent light resistance.SOLUTION: A resin composition contains (1) a transparent resin and (2) a filler. The filler (2) is at least one of (2-1) a layer compound obtained by salt exchange of a layer mineral with an organic onium salt, and (2-2) a polymer nanocomposite obtained by polymerizing a radical polymerization initiator having a group represented by the general formula (I) with a polymerizable monomer using a layer mineral immobilized on the interlayer surface. The content of the filler (2) based on 100 pts.mass of the transparent resin (1) is 0.1-30 pts.mass. 【課題】高い透明性を保持しているとともに、耐光性に優れた樹脂組成物を提供する。【解決手段】（１）透明樹脂と、（２）フィラーとを含有し、（２）フィラーが、（２−１）層状鉱物を有機オニウム塩で塩交換して得られる層状化合物と、（２−２）下記一般式（Ｉ）で表される基を有するラジカル重合開始剤がその層間表面に固定化された層状鉱物を用いて重合性モノマーを重合させて得られた高分子ナノコンポジットの少なくともいずれかであり、（１）透明樹脂１００質量部に対する（２）フィラーの含有量が、０．１〜３０質量部である樹脂組成物を提供する。【選択図】なし
