1. An olefin-based polymer satisfying the following conditions (1) to (3):
(1) a melt index (MI, 190° C., 2.16 kg load conditions) is from 0.1 g/10 min to 10.0 g/10 min,
(2) a density (d) is from 0.860 g/cc to 0.880 g/cc, and
(3) T(90)−T(50)≤50 and T(95)−T(90)≥10,
wherein T(50), T(90) and T(95) are temperatures at which 50%, 90%, and 95% of the olefin-based polymer are melted, respectively, when fractionating a temperature-heat capacity curve from measurement results by a differential scanning calorimetry precise measurement method (SSA).
