[Solution] The aforementioned problem is resolved by providing a first sheet layer (12S) comprising a nonwoven fabric, a second sheet layer (12H) facing one surface of the first sheet layer (12S) and comprising a nonwoven fabric, and, between the two sheet layers, a plurality of slender, elongate elastically stretchable members (19) provided extending in the stretch direction with spaces therebetween. At least a part of both ends of the elastically stretchable members (19) are affixed to at least one among the first sheet layer (12S) and the second sheet layer (12H) by only a first hot melt adhesive (71). The first sheet layer (12S) and the second sheet layer (12H) are bonded by a second hot melt adhesive (72) in a stretch direction range corresponding to the space between both ends of the elastically stretchable members (19).
