The present invention is a thermoplastic resin composition which is obtained by adding a specific modified vinyl copolymer having a specific intrinsic viscosity to a composition comprising a styrene -based resin and a polyamide resin. The thermoplastic resin composition has excellent flowability and has a far better surface appearance than conventional ones while satisfactorily retaining rigidity, heat resistance, chemical resistance, and impact resistance at room and low temperatures.
