An ethylene-&#x3b1;-olefin copolymer capable of implementing formation of a film having excellent slipperiness and suppressed fish eyes, a method of producing the ethylene-&#x3b1;-olefin copolymer, an ethylene-based resin composition containing the ethylene-&#x3b1;-olefin copolymer, and a film containing the ethylene-&#x3b1;-olefin copolymer or the ethylene-based resin composition. An ethylene-&#x3b1;-olefin copolymer according to the present invention has: a monomer unit (1) based on ethylene; and a monomer unit (2) based on an &#x3b1;-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.

Ethylene-&#x3b1;-olefin copolymer, method of producing ethylene-&#x3b1;-olefin copolymer, ethylene-based resin composition, and film

There is provided a thermoplastic elastomer composition from which a molded article having an appearance suitable for non-painting use can be produced. In the thermoplastic elastomer composition containing at least two olefin polymers, a content of an insoluble component in ortho-dichlorobenzene at 140&#xb0; C. is 20 wt % to 50 wt % and an isothermal crystallization time measured at 130&#xb0; C. is 300 seconds or longer.
