To provide a reinforced aromatic polycarbonate resin composition exhibiting not only excellent mechanical strength causing no delamination, flow properties and external appearances of a molded article but also good heat resistance that comprises as a base material a polycarbonate resin reinforced by a silicate mineral.

The reinforced aromatic polycarbonate resin composition comprises 100 pts.wt. of the total of 40-99 pts.wt. of an aromatic polycarbonate resin (component A) and 1-60 pts.wt. of the silicate mineral (component B), and 0.05-30 pts.wt. of a flow modifier (component C), where the flow modifier (component C) is a copolymer (i) comprising, as a main constituting unit, a unit formed from a (meth)acrylate monomer (Ca) represented by a specific formula and an aromatic alkenyl compound monomer (Cb) and (ii) containing a chloroform-soluble component having a weight-average molecular weight of 10,000-200,000.
