An aromatic polycarbonate resin composition comprising:(1) 10 to 90 wt % of an aromatic polycarbonate resin (component A) which is obtained from an ester exchange reaction between a diphenol and a dicarbonate ester and has a terminal hydroxyl group concentration of 10 to 70 mol % based on 100 molt of the total of all the terminal groups; and(2) 90 to 10 wt % of a thermoplastic graft copolymer resin (component B) which is obtained by grafting a vinyl cyanide monomer component and an aromatic vinyl monomer component to a diene-based rubber, the proportion of the vinyl cyanide monomer component to the copolymer resin being 10 to 27 wt % and the amount of a vinyl cyanide monomer contained in the copolymer resin being 200 ppm or less. According to the present invention, there is provided an aromatic polycarbonate resin composition which has excellent mechanical strength, particularly falling weight impact strength and improved hydrolysis resistance under a moist heat environment.
