    Abstract: PROBLEM TO BE SOLVED: To provide a resin composition that excels in impact resistance, heat resistance, moldability and chemical resistance, and is suitable as a molding material or the like of a portable terminal housing.SOLUTION: An aromatic polycarbonate based composite resin composition includes: 3-20 pts.mass of a graft copolymer (C) that graft-polymerizes a (meth)acrylic acid ester compound to a diene rubber; and 0.005-0.1 pt.mass of a stabilizer (D) based on 100 pts.mass of a resin component consisting of 60-90 pts.mass of an aromatic polycarbonate resin (A) and 10-40 pts.mass of a polyester resin (B). The graft copolymer (C) is such that a sulfur content is 100-1,500 ppm, and an average particle diameter is 70-240 nm, and the stabilizer (D) is an organic phosphate compound shown by the following general formula (I): O=P(OH)(OR)(in the formula, R is an alkyl group or an aryl group; m is 0-2).
