The present invention relates to a resin composition containing: 5 to 82 parts by weight of an aromatic polyester (component A); 0 to 50 parts by weight of an aromatic polycarbonate (component B) having a deflection temperature under load (A method) of 110°C or higher and 140°C or lower: 10 to 90 parts by weight of a highly heat-resistant aromatic polycarbonate (component C) having a deflection temperature under load (A method) of 145°C or higher; 0 to 10 parts by weight of a graft-copolymer (component D) containing 40 to 90% by weight of a rubbery polymer; 0 to 10 parts by weight of an ethylene copolymer (component E); 2.5 to 50 parts by weight of a silicate filler (component F); 0 to 10 parts by weight of an electric conductive filler (component G); and 0 to 2 parts by weight of a phosphorus compound (component H), provided that the total amount of the all components are 100 parts by weight, wherein the total amount of the component D and the component E is from 0.5 to 10 parts by weight, and the resin composition has a deflection temperature under load (A method) of 130°C or higher. When the resin composition is used, a resin molded article suitable for an automobile exterior or outer panel member can be provided, which maintains a coating appearance consistency with a metal site, has a heat resistance capable of coping with an high temperature exposure during the baking of the coating material, has a good surface property, has an inhibited deformation caused by a linear thermal expansion or humidity change, is light, has excellent rigidity, impact property, chemical resistance, and coating layer adhesion, and has a good flowability during processing.
