The present invention provides a hot melt adhesive for high-speed coating and spiral coating at low temperature. The hot melt adhesive has excellent adhesion to polyethylene and nonwoven fabric, and is suitable for disposable products. The hot melt adhesive comprises: (A) a propylene homopolymer having a melting point of 100° C. or lower which is obtainable by polymerizing propylene using a metallocene catalyst; and (B) an ethylene-based copolymer.
