Abstract: A polypropylene resin composition contains components (A), (B) and (C). A content of (A) is from 70 to 90 parts by weight, a content of (B) is from 10 to 30 parts by weight, and a content of (C) is from 1 to 5 parts by weight, when the total of the content of (A) and (B) is taken as 100 parts by weight. (A) polypropylene, (B) talc having an average particle diameter of 1 μm to 8 μm, (C) polyethylene glycol, wherein a molecular weight at the maximum point of refractive index intensity in a chromatogram obtained by gel permeation chromatography using a differential refractometer is from 2,000 to 4,000, and S2/S1 is from 1.3 to 2.0, where peak areas S2 and S1 are as defined herein.
