摘要： A resin composition, a shaped article, a fiber, a film and a sheet. The resin composition includes two or more kinds of polyolefin resins (A), and 0.05 to 10 mass % of an α-olefin (co)polymer (B) satisfying requirements (b-1) to (b-3): (b-1) A methyl group index is 40 to 60%. The methyl group index is a ratio of an integral of a peak observed in a range of 0.50 to 1.15 ppm to an integral of peaks observed in a range of 0.50 to 2.20 ppm in a 1H-NMR spectrum of a solution of the (co)polymer (B) in deuterated chloroform, positions of the peaks being calculated relative to a solvent peak at 7.24 ppm assigned to CHCl3 in deuterated chloroform as a reference. (b-2) A weight average molecular weight determined by GPC is 1,500 to 20,000. (b-3) No melting point is observed from −100 to 150° C. in DSC.
