Abstract
An ethylene-α-olefin copolymer, wherein the ethylene-α-olefin copolymer has a density of 860 to 950 kg/mand a melt flow rate of 0.01 to 100 g/10 min, wherein in a molecular weight curve measured by gel permeation chromatography, the molecular weight of the copolymer providing the highest peak exists within the range of 10,000 to 20,000, wherein the height of the peak at a molecular weight of 177,000 is 5 to 30% where the height of the highest peak is 100%, wherein a characteristic relaxation time of the copolymer satisfies a relation represented by formula (1), and wherein the ethylene-α-olefin copolymer exhibits more than one melt peak observed by a differential scanning calorimeter.40.2×MFR<τ<71.8×MFR  (1)
