Abstract
An ethylene-α-olefin copolymer capable of implementing formation of a film having excellent slipperiness and suppressed fish eyes, a method of producing the ethylene-α-olefin copolymer, an ethylene-based resin composition containing the ethylene-α-olefin copolymer, and a film containing the ethylene-α-olefin copolymer or the ethylene-based resin composition. An ethylene-α-olefin copolymer according to the present invention has: a monomer unit (1) based on ethylene; and a monomer unit (2) based on an α-olefin having 3 to 20 carbon atoms, wherein a branching parameter is 0.70 to 0.90, and a light scattering area ratio is 1.60 to 3.60.
