Provided is a hot-melt adhesive which satisfies both solidification rate and adhesiveness. A base polymer for a hot-melt adhesive which satisfies the following (1) and (2): (1) a modulus of elasticity in tension at 23°C is 400 MPa or less: and (2) a semi-crystallization time at 23°C is 20 minutes or less.
