Abstract
An ethylene-α-olefin copolymer comprising monomer units derived from ethylene and monomer units derived from an α-olefin having 3 to 20 carbon atoms, having a density (d) of 860 to 950 kg/m3, having a melt flow rate (MFR) of 0.01 to 100 g/10 min, having a bimodal molecular weight distribution, and having a single melting peak measured by a differential scanning calorimeter (DSC).
