Zusammenfassung:	Provided are a propylene-based polymer which enhances heat creep resistance and a hot-melt adhesive having excellent heat creep resistance. A propylene-based polymer which satisfies the following (1) and (2): (1) 125 ‰¤ a modulus of elasticity in tension (MPa) at 23°C ‰¤ 400; and (2) 100 ‰¤ an elongation at break (%) at 23°C ‰¤ 1,000, and a hot-melt adhesive containing the propylene-based polymer in an amount of 1 to 50% by mass.
