Abstract: An object of the present invention is to provide a hot melt adhesive which is excellent in high-speed coating and spiral coating at low temperature, and is also excellent in adhesion to polyethylene and a nonwoven fabric; and disposable products obtainable by using the hot melt adhesive. A hot melt adhesive including: (A) a thermoplastic block copolymer which is a copolymer of a vinyl-based aromatic hydrocarbon with a conjugated diene compound; and (B) a propylene homopolymer having a melting point of 100°C or lower which is obtainable by polymerizing propylene using a metallocene catalyst, is excellent in high-speed coating and spiral coating at low temperature, and is also excellent in adhesion to a nonwoven fabric and a polyethylene film. Since disposable products obtainable by using the hot melt adhesive are produced at low temperature using a high-speed coating line, the disposal products are produced efficiently and safely, and a nonwoven fabric and a polyethylene film of the disposable products are less likely to peel.
