Abstract:
1. A resin composition comprising 40% by weight to 90% by weight of a propylene polymeric material (A) containing 50% by weight or more of structural units derived from propylene, 9% by weight to 30% by weight of wollastonite (B), and 1% by weight to 30% by weight of an elastomer (C) where the combined amount of (A), (B) and (C) is taken as 100% by weight, wherein the wollastonite (B) satisfies the following requirement (1) and requirement (2), requirement (1): having an average fiber length of 10.0 μm to 26.0 μm requirement (2): having a fiber length distribution satisfying the following (b1), (b2) and (b3) where the overall number of the wollastonite is taken as 100%, (b1): the content of wollastonite having a fiber length of 50 μm or more is 0.1% to 3.0% (b2): the content of wollastonite having a fiber length of not less than 10 μm but less than 50 μm is 17.0% to 35.0% (b3): the content of wollastonite having a fiber length of less than 10 μm is 62.0% to 82.9%.
