PROBLEM TO BE SOLVED: To provide a polyester resin composition excellent in rigidity, impact resistance, particularly appearance of its molding by improving insufficient points of a conventional polyester. SOLUTION: A polyester resin composition comprises to (A) 100 pts.wt. of a thermoplastic polyester; (B) 0.1-40 pts.wt. of a phyllosilicate wherein an exchangeable cation existing between layers is exchanged with an organic onium ion; (C) 0.001-5 pts.wt. of at least one of benzophenone, benzotriazole and cyanoacrylate compounds; and (D) 0.001-5 pts.wt. of at least one of hindered phenol, phosphite and thioether compounds to (A) 100 pts.wt. of the thermoplastic polyester.
