PROBLEM TO BE SOLVED: To obtain an aromatic polucarbonate resin composition capable of simultaneously improving molding heat resistance, resistance to dry heating and resistance to wet heat fatigue while retaining mold release characteristics by combinedly using specific compounds as stabilizing agent and limiting the chorine concentration of the stabilizing agent. SOLUTION: The aromatic polyucarbonate resin composition includes (A) 100 pts.wt. of an aromatic polycarbonate resin having viscosity average molecular weight of 10,000-50,000, (B) 0.0001-0.15 pt. of a phosphorus based stabilizer composition comprising compounds expressed by formulas I-III (Ar1 and Ar2 are each an (alkyl)phenyl group; Ar3 is a dialkylphenyl group), including 40-80 wt.% of the compound of formula I, 0.25% (preferably 5-25%) of the compound of formula II and 5-50% of the compound of formula III and the sum of the compound of formulas I-III is 100 wt.%, and the concentration of the chlorine atom and the chloride ions is 1-11,000 ppm, and (c) 0.001-1.0 pt. (preferably 0.01-0.6 pt.) of an internal mold release agent comprising >=90% ester of an alcohol and a fatty acid.
