The present invention relates to an olefin-based polymer satisfying requirements: (1) a melt index (MI, 190° C., 2.16 kg load conditions) ranging from 1.0 to 10.0 g/10 min; (2) a density (d) ranging from 0.875 to 0.895 g/cc; (3) 0.5 J/g≤dH(100)≤3.0 J/g and 1.0 J/g≤dH(90)≤6.0 J/g as measured by successive self-nucleation/annealing (SSA) using a differential scanning calorimeter (DSC); (4) 15≤T(90)−T(50)≤30 and 50° C.≤T(50)≤75° C. as measured by SSA using a DSC; and (5) a melting point (Tm) of 55° C.≤Tm≤80° C. as measured using a DSC. The olefin-based polymer according to the present invention is a low-density olefin-based polymer and has a highly crystalline region introduced therein, thereby exhibiting high mechanical stiffness.
