When the absorbent article is removed, the ventral portion and the back side are continuously and stably separated by the same force.The absorbent article 1 includes a ventral portion 11 and a back side portion 13, and each of the lateral end portions 11e and 13e of the ventral portion and the back side portion of the absorbent article 1 is joined to each other in the thickness direction and joined to each other and joined to each other.The junction includes a plurality of fusion portions 30 arranged in the longitudinal direction.The fusion portion includes a core portion MC and a peripheral wall portion SW extending in the thickness direction from the periphery of the core portion to the cylinder.The surface of the core is flat.In the peeling test of the junction, the graph showing the load applied between the jig to the spacing between the jig holding the sample is generally at the positions of the plurality of fusion portions, and there is a convex portion showing the maximum value, and the standard deviation for the average value of the maximum value in the plurality of convex portions is 3N or less.Diagram【課題】吸収性物品の取り外し時、腹側部と背側部とを概ね同じ力で連続的・安定的に分離する。【解決手段】吸収性物品１は、腹側部１１と背側部１３とを備え、腹側部及び背側部の横方向の端部１１ｅ、１３ｅ同士が縦方向に沿い厚さ方向に重なり互いに接合された接合部１４ａを含む。接合部は、縦方向に沿って配置された複数の融着部３０を含む。融着部は、コア部ＭＣと、コア部の周縁から筒状に厚さ方向に延びる周壁部ＳＷと、を含む。コア部の表面は平坦である。接合部の剥離試験で、試料を保持する冶具間の間隔に対する冶具間に掛かる荷重を示すグラフは、概ね複数の融着部の各々の位置で、荷重が極大値を示す凸部を有し、複数の凸部における極大値の平均値に対する標準偏差は３Ｎ以下である。【選択図】図２
