PROBLEM TO BE SOLVED: To provide an absorbent article in which the adhesion force between film materials is stronger than the tension.SOLUTION: In the disposable absorbent article, the two neighboring film materials are joined with a hot-melt adhesive. The blending quantity of a styrene-butadiene copolymer composition in the hot-melt adhesive is 5-50 mass% of the total and the melt viscosity of the composition at 130°C is 10,000-20,000 mPa s. The styrene-butadiene copolymer composition includes a styrene-butadiene diblock copolymer and a styrene-butadiene-styrene triblock copolymer. The proportion of the diblock copolymer to the triblock copolymer is 2.1 or more.
