Claim 9:
10. A method for producing the polycarbonate resin composition according to claim 2, comprising:
a first step of melt-kneading 28 to 50% by mass of olefin polymer (B), 40 to 70% by mass of basic magnesium sulfate (C) selected from fibrous basic magnesium sulfate (C-1) and fan-shaped basic magnesium sulfate (C-2), and 0.1 to 5% by mass of at least one (D) selected from a fatty acid metal salt and a fatty acid to obtain masterbatch pellets; and
a second step of melt-kneading the masterbatch pellets, polycarbonate resin (A), and elastomer (E) to produce the polycarbonate resin composition.
