ABSTRACT:
A polyester resin composition containing a thermoplastic polyester resin; a polyester copolymer containing a monomer having at least one of an amino group, an imino group, an amido group, and a sulfonic acid group; a layered silicate; and an antioxidant. The monomer having at least one of an amino group, an imino group, an amido group, and a sulfonic acid group is contained in the polyester copolymer in an amount of 5 to 15 mol %. The monomer having at least one of an amino group, an imino group, an amido group, and a sulfonic acid group is contained in the polyester resin composition in an amount of 1 to 5 mol % based on a total polyester content of the polyester resin composition. The antioxidant is contained in the polyester resin composition in an amount of 0.01% to 1.0% by mass.
