Polyolefin resin composition and molded article

A polyolefin resin composition containing the hydrogenated block copolymer (A) and the polyolefin resin (B), the hydrogenated block copolymer (A) contains a structural unit derived from an aromatic vinyl compound weight a polymer block (a), polymer block containing 1 to 100 wt% of the structural unit (b1) derived farnesene, containing 99-0 wt% of a conjugated diene-derived structural unit (b2) other than the farnesene (b) wherein the door, a polymer weight ratio of the block (a) and the polymer block (b) [(a) / (b)] is 1 / 99-55 / 45, the polymer block (b) in the carbon - carbon double bonds are those formed by hydrogenated over 50 mol%, the mass ratio of the polyolefin resin (B) and the hydrogenated block copolymer (a) [the polyolefin resin (B) / hydrogenated block copolymer A)] is 1 / 99-99 / 1, a polyolefin resin composition, flexibility, good moldability, excellent in weather resistance and whitening resistance, and also excellent in rigidity.
