    • The present invention relates to a method for producing an aromatic polycarbonate resin composition, comprising the steps of:
      dissolving an aromatic polycarbonate resin-A having a viscosity-average molecular weight of 11,000-21,000 and an aromatic polycarbonate resin-B having a viscosity-average molecular weight of 67,000-85,000 in a solvent; and
      removing the solvent from the resulting resin solution,
      wherein said aromatic polycarbonate resin composition comprises_an alkali metal salt of an organic sulfonic acid and the content of the alkali metal salt of the organic sulfonic acid is 0.005-0.1% by mass relative to the total mass (100% by mass) of the aromatic polycarbonate resin-A and the aromatic polycarbonate resin-B,
      wherein the aromatic polycarbonate resin-A is contained in an amount of 60-90% by mass and the aromatic polycarbonate resin-B is contained in an amount of 10-40% by mass relative to the total amount of the aromatic polycarbonate resin-A and the aromatic polycarbonate resin-B, and
      wherein a haze value of a plate-like molded article having a thickness of 3.0 mm molded from the aromatic polycarbonate resin composition is 2% or lower, the number of unmelted polycarbonate pieces having a long diameter of 100 µm or more existing within a region of 5 cm x 3 cm of the plate-like molded article is 10 or less and a test specimen for UL test having a thickness of 1.2 mm molded from the aromatic polycarbonate resin composition satisfies the UL-94 V-0 standard.
