PROBLEM TO BE SOLVED: To provide a hot melt adhesive capable of high speed coating, excellent in adhesiveness with wet state and low temperature coating and suitable for disposable product applications with less odor.SOLUTION: A hot melt adhesive containing (A) a propylene homopolymer obtained by polymerizing propylene by using a metallocene catalyst and having the melting point of 100°C or less and (B) wax modified by carboxylic acid and/or carboxylic acid anhydride is suitable for high speed coating and excellent in wet adhesiveness and low temperature coating. The wet adhesiveness of the (B) wax modified by carboxylic acid and/or carboxylic acid anhydride is further improved in the case that it is polyolefin wax modified by maleic acid and/or maleic acid anhydride.SELECTED DRAWING: None
