A resin composition containing (A) a thermoplastic polyurethane; (B) a polymer having a hydroxyl group at the end of the molecular main chain, the main chain principally comprising a conjugated diene compound unit (I) which may or may not be hydrogenated and an aromatic vinyl compound unit (II); and (C) a polyacetal resin, at ratios of (A), (B) and (C) being 2.5 to 90% by weight, 2.5 to 90% by weight and 5 to 95% by weight, respectively, on the basis of the total weight of the (A), (B) and (C), is excellent in terms of tensile strength and tensile elongation, and impact resistance at ambient temperature and lower temperatures.
