摘要：
There is provided a polypropylene resin composition comprising 50 to 99% by weight of a polypropylene resin (A), which contains a propylene homopolymer and/or a propylene-ethylene random copolymer containing 1.0% by weight or less of ethylene units, and 1 to 50% by weight of boehmite (B) having a BET specific surface area of 20 to 80 m2/g, c-axis length of 30 to 300 nm, and a ratio of a-axis length to b-axis length (a-axis length/b-axis length) of 5 or more, provided that the total of the polypropylene resin (A) and boehmite (B) is 100% by weight.
