The polycarbonate resin composition according to the present invention includes: 50 to 90% by mass of polycarbonate resin (A); 2.0 to 20% by mass of olefin polymer (B); 5 to 40% by mass of basic magnesium sulfate (C) selected from fibrous basic magnesium sulfate (C-1) and fan-shaped basic magnesium sulfate (C-2); 0.1 to 8% by mass of at least one (D) selected from a fatty acid metal salt and a fatty acid; and 1 to 20% by mass of elastomer (E).

Polycarbonate resin composition, method for producing the same, masterbatch pellet, and molded body

A filler composition comprising fibrous basic magnesium sulfate particles and non-fibrous inorganic micro-particles having an average particle diameter in the range of 0.001 to 0.5 &#x3bc;m in a ratio by weight in the range of 100:0.001 to 100:50, and a polyolefin resin composition comprising a polyolefin resin, fibrous basic magnesium sulfate particles and non-fibrous inorganic micro-particles having an average particle diameter in the range of 0.001 to 0.5 &#x3bc;m, in which the polyolefin resin and fibrous basic magnesium sulfate particles are present in a weight ratio of 99:1 to 50:50, and the non-fibrous inorganic micro-particles are present in an amount of 0.001 to 50 weight parts per 100 weight parts of the basic fibrous magnesium sulfate particles and/or in an amount of 0.0002 to 10 weight parts, per 100 weight parts of the resin.
