To provide an aromatic polycarbonate resin composition which has an impact resistance improved by blending of an impact strength improver and which also has an excellent transparency and a good surface hardness. The aromatic polycarbonate resin composition includes, with respect to 100 parts by mass of a resin component containing 55 to 85 percent by mass of an aromatic polycarbonate resin (A) having a mass average molecular weight of 15,000 to 40,000 and 15 to 45 percent by mass of a (meth)acrylate copolymer (B) which has a mass average molecular weight of 5,000 to 30,000 and which is composed of an aromatic (meth)acrylate unit (b1) and a methyl (meth)acrylate unit (b2) at a mass ratio (b1/b2) of 5 to 50/50 to 95, 1 to 20 parts by mass of an impact strength improver (C). A refractive index nab of the resin component at a wavelength of 589 nm and a refractive index nc of the impact strength improver (C) at a wavelength of 589 nm satisfy the following formula i). −0.01≦nab−nc≦+0.01 Formula i)
