An object of the present invention is to achieve both flexibility and fixability of an elastic elastic member in a case where an elastic elastic member is fixed and a first sheet layer and a second sheet layer are bonded by a hot melt adhesive. The object is to provide a first sheet layer 12S made of non-woven fabric, a second sheet layer 12H made of non-woven fabric facing one surface of the first sheet layer 12S, the first sheet layer 12S and the second sheet layer 12S. Between the sheet layers 12H, there are provided a plurality of slender elastic elastic members 19 provided along the expansion / contraction direction and spaced apart from each other, and both ends of the elastic expansion / contraction member 19 are provided with the first hot melt. It is fixed to at least one of the first sheet layer 12S and the second sheet layer 12H via an adhesive 71, and the first sheet layer 12S and the second sheet layer 12H are between the both ends of the elastic elastic member 19. It is joined via the second hot melt adhesive 72 in the corresponding stretch direction range, and the holding power of the first hot melt adhesive 71 is higher than the holding power of the second hot melt adhesive 72. Yo It is solved.
