PROBLEM TO BE SOLVED: To obtain the subject composition capable of forming a molded product having high imparted strength retention in welded portions without causing the deterioration of mechanical characteristics by adding an ABS-based resin and a specific epoxy-modified copolymer to an aromatic polycarbonate resin. SOLUTION: This aromatic polycarbonate-based resin composition comprises (A) 40-97 pts.wt. of an aromatic polycarbonate for example, an aromatic polycarbonate having repeating units of the formula [R is phenylene (substituted by a halogen or the like); A and B are each H or a 1-12C hydrocarbon group excluding aliphatic unsaturated groups]}, (B) 60-3 pts.wt. of an ABS-based resin (for example, a composition of an acrylonitrile-butadiene-styrene copolymer resin and an acrylonitrile-styrene copolymer), and (C) an epoxy-modified (partially hydrogenated) aromatic vinylic block copolymer [for example, the epoxidation product of a (partially hydrogenated) styrene-butadiene-styrene block copolymer having a styrene content of 1-60 wt.%] in an amount of 0.5-30 pts.wt. per 100 pts.wt. of the total amount of the components A and B.
