Abstract: A resin composition is provided which is excellent in impact resistance, heat resistance, moldability, and chemical resistance and which is suitable, for example, as a molding material for a portable terminal housing. An aromatic polycarbonate composite resin composition contains, with respect to 100 parts by mass of a resin component formed of 60 to 90 parts by mass of an aromatic polycarbonate resin (A) and 10 to 40 parts by mass of a polyester resin (B), 3 to 20 parts by mass of a graft copolymer (C) formed by graft polymerization of a (meth)acrylic acid ester compound with a diene-based rubber and 0.005 to 0.1 parts by mass of a stabilizer (D). The graft copolymer (C) has a sulfur content of 100 to 1,500 ppm and an average particle diameter of 70 to 240 nm, and the stabilizer (D) is an organic phosphate compound represented by the following general formula (I). O═P(OH)m(OR)3-m  (I) R represents an alkyl group or an aryl group. m represents 0 to 2.
