The purpose of the present invention is to make a sheet member of an absorbent article less susceptible to tearing when taking off the absorbent article and allow the ventral side portion and dorsal side portion to be appropriately separated. This absorbent article comprises a ventral side portion (11) and a dorsal side portion (13) and includes bonded portions (14a) formed by the lateral ends (11e, 13e) of the ventral side portion and the dorsal side portion being longitudinally placed on top of one another in a thickness direction and bonded to each other. The bonded portions include a plurality of fused portions (30) that are longitudinally arranged. Each fused portion includes a core portion MC at which a ventral side sheet member and a dorsal side sheet member are fused in the thickness direction and a surrounding wall portion SW which extends tubularly in the thickness direction from the peripheral edge of the core portion with the ventral side sheet member and the dorsal side sheet member being fused in the thickness direction thereat. In a peel strength test for the bonded portion, a ratio a/b of 0.5 to 2.0 is obtained for the ratio of the area a of the narrow spacing region and the area b of the wide spacing region in the region bounded by a graph plotting the relationship between the load between jigs that hold a sample compared against the spacing between the jigs, the narrow spacing region and the wide spacing region being separated at the maximum load spacing as a boundary.Le but de la présente invention est de rendre un élément en feuille d'un article absorbant moins sensible au déchirement lors du retrait de l'article absorbant et de permettre une séparation appropriée de la partie côté ventral et de la partie côté dorsal. Cet article absorbant comprend une partie côté ventral (11) et partie côté dorsal (13) et comprend des parties liées (14a) formées par les extrémités latérales (11e, 13e) de la partie côté ventral et de la partie côté dorsal qui son
