An aromatic polycarbonate resin composition superior in thermal stability, flame retardancy, and light reflectivity, and a light reflective member consisting of a molded article of the resin. An aromatic polycarbonate resin composition comprising, 3 to 30 parts by weight of a titanium oxide-based additive (B) which has been surface-treated with alumina and organosiloxane, 0.01 to 1 parts by weight of a metal salt of aromatic sulfonic acid (C), and 0.05 to 0.9 parts by weight of polytetrafluoroethylene (D) based on 100 parts by weight of an aromatic polycarbonate resin (A), characterized in that an aluminium content a (wt%), a carbon content c (wt%) in the titanium oxide-based additive (B), and an average particle size d (µm) of titanium oxide satisfy the following (1) and (2): 6.5 ¤ a / d 2 ¤ 15 5 ¤ c / d 2 ¤ 25 |
