Abstract
An object of the present invention is to provide a resin composition which is increased in heat resistance (high crystallinity) and transparency without impairing rigidity which a thermoplastic resin inherently has and a molded article containing the resin composition. A thermoplastic resin composition relating to the present invention includes a thermoplastic resin (A) and a crystal nucleating agent (B) composed of tris(amino acid ester)amides of trimesic acid. The crystal nucleating agent (B) is preferably tris(valine ester)amides of trimesic acid or tris(leucine ester)amides of trimesic acid, and the thermoplastic resin (A) is preferably a lactic acid resin and more preferably a polylactic acid.
