1. An aromatic polycarbonate resin composition, comprising:

  • with respect to 100 parts by mass of a resin component comprising;

    (A) 55 to 85 percent by mass of an aromatic polycarbonate resin (A) having a mass average molecular weight of 15,000 to 40,00; and

    (B) 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 comprises(b1) an aromatic (meth)acrylate unit (b1), and(b2) a methyl (meth)acrylate unit (b2),(C) 1 to 20 parts by mass of an impact strength improver (C),wherein;

    in the (meth)acrylate copolymer (B), a mass ratio (b1/b2) is 5 to 50/50 to 95; and

    when the refractive index of the resin component at a wavelength of 589 nm is represented by nab, and the refractive index of the impact strength improver (C) at a wavelength of 589 nm is represented by nc, nab and nc satisfy formula (1);
