The present invention addresses the problem of preventing wrinkles in the MD direction of a top sheet (30) while preventing a reduction in flexibility or a deteriorated appearance, when the top sheet (30) having a pushing protrusion section (31) and a second sheet (40) are joined. The problem is solved as follows. The pushing protrusion section (31) is formed through an embossing process while transferring a non-woven fabric (30S) that becomes the top sheet (30) by pulling the fabric from the downstream side of a manufacturing line. Then, a material (40S) for the second sheet (40) is aligned on a rear surface of the non-woven fabric (30S) on which the pushing protrusion section (31) is formed. Top/second joining sections (80) are then formed in a region between the pushing protrusion sections (31) adjacent to one another in the MD direction such that a plurality of rows, which are aligned to be spaced apart from each other in the CD direction, cross a central position of the region in the CD direction. At the same time, in a gap portion (81) between the top/second joining sections (80) in the CD direction, the material (40S) of the second sheet (40) and the non-woven fabric (30S) are not fused, but are joined in a pattern in which the non-woven fabric (30S) is compressed.Le problème posé par la présente invention concerne la prévention des plis dans la direction MD d'une feuille supérieure (30) tout en empêchant une réduction de flexibilité ou un aspect détérioré, lorsque la feuille supérieure (30) ayant une section de saillie de poussée (31) et une seconde feuille (40) sont jointes. La solution de l'invention porte sur ce qui suit. La section de saillie de poussée (31) est formée par le biais d'un processus de gaufrage, tout en transférant une étoffe non tissée (30S) qui devient la feuille supérieure (30) en tirant l'étoffe depuis le côté aval d'une chaîne de fabrication. Ensuite, un matériau (40S) pour la seconde feuille (40) est aligné sur une surface arrière de
