The present invention relates to a resin composition that contains 5-82 parts by weight of an aromatic polyester (component A), 0-50 parts by weight of an aromatic polycarbonate having a deflection temperature under load (as measured using the A method) of 110-140°C (component B), 10-90 parts by weight of a highly heat-resistant aromatic polycarbonate having a deflection temperature under load (as measured using the A method) of 145°C or higher (component C), 0-10 parts by weight of a graft copolymer containing 40-90 wt.% of a rubbery polymer (component D), 0-10 parts by weight of an ethylene-based copolymer (component E), 2.5-50 parts by weight of a silicate-based filler (component F), 0-10 parts by weight of an electrically conductive filler (component G) and 0-2 parts by weight of a phosphorus compound (component H) (here, the total quantity of all the components is 100 parts by weight), wherein the total quantity of component D and component E is 0.5-10 parts by weight, and the deflection temperature under load (as measured using the A method) of the composition is 130°C or higher. By using this resin composition, it is possible to provide a resin molded body which is suitable for use as an exterior material/exterior panel member of an automobile, which ensures a coating appearance that is consistent with a metal portion, which exhibits heat resistance that can endure exposure to high temperatures during baking of a coating material, exhibits good surface characteristics, for which deformation caused by changes in coefficient of linear thermal expansion or humidity is suppressed, is lightweight, excellent in rigidity, impact properties, chemical resistance and adhesion to a coating film, and which exhibits good fluidity during processing. |
