Claim Text:
1. An ethylene copolymer obtained by polymerization of ethylene and a (C3-C18) α-olefin co-monomer, the ethylene copolymer being injection-moldable, wherein the ethylene copolymer has a density of 0.91 to 0.94 g/cm 3 and a melt index (MI) of 3 to 50 g/10 min, a molecular weight distribution index 1.98 to 2.21 as measured by mass average molecular weight divided by number average molecular weight, and satisfies Formulas 1 and 2 below: in Formulas 1 and 2, S (wt %) represents an extract content of the ethylene copolymer at 35° C. after 10 minutes as measured by temperature rising elution fractionation analysis using 1,2,4-trichlorobenzene as a solvent, and D (g/cm
