PROBLEM TO BE SOLVED: To provide a hot-melt adhesive in which at least one kind selected from the magnitude of adhesion and holding properties of the hot-melt adhesive to a member of a paper diaper, a high level of softening point, a low level of viscosity and a high level of thermal stability is improved. SOLUTION: The hot-melt adhesive comprises (I) component: a block copolymer, (II) component: a pressure-sensitive adhesion imparting agent and (III) component: a plasticizer. The component (I) contains≥30 wt% of (A) a styrene-butadiene-styrene block copolymer having 35-50 wt.% styrene content, 50-80 wt.% of styrene-butadiene diblock content and 20-40 mPas viscosity of a 15 wt.% solution in toluene at 25°C. The component (I) is contained in an amount of 17-30 wt.% based on the sum total of the components (I), (II) and (III). COPYRIGHT: (C)2004,JPO
