PROBLEM TO BE SOLVED: To obtain an aromatic polycrbonate resin composition capable of simultaneously improving molding heat resistance, resistance to dry heating and resistance to wet heat fatigue while retaining weatherability by combinedly using specific stabilizers and limiting the chlorine concentration of the stabilizers. SOLUTION: This aromatic polycarbonate resin composition includes (A) 100 pts.wt. of an aromatic polycarbonate resin having viscosity average molecular weight of 10,000-50,000, (B) 0.005-0.06 pt. of a phosphorus based stabilizing agent comprising compound expressed by formula I (Ar1 is an (alkyl)phenyl group and the concentration of the chlorine atoms and the chloride ions is 1-11,000 ppm, (C) 0.02-0.20 pt. of a phosphorus based stabilizer comprising compound expressed by formula II (Ar2 is a dialkylphenyl group) and the concentration of the chlorine atoms and the chloride ions is 0.1-50 ppm, (D) 0.01-1.5 pts. of a benzotriazole based ultraviolet stabilizer, (E) 0-1.0 pt. of an internal mold release agent comprising >=90% ester of an alcohol and a fatty acid and (F) 0-0.15 pt. of a hindered phenol based stabilizer.
