PROBLEM TO BE SOLVED: To provide a hot melt adhesive that has high fluidity during when melted, exhibits high adhesive strength between PP nonwoven fabrics, and has high adhesiveness with PE film/PP nonwoven fabric and long-term stability. ! SOLUTION: A hot melt adhesive comprises (A) a propylene homopolymer that satisfies (i) to (iii) below and (B) a styrene random copolymer: (i) the tensile modulus of elasticity at 23°C is 400 MPa or less, (ii) the weight-average molecular weight (Mw) is 10,000 to 150,000, and (iii) Mw/Mn is 2.5 or less. !
