PROBLEM TO BE SOLVED: To suppress deterioration of touch in an absorbent article having leakage prevention walls.SOLUTION: An absorbent article has: an absorber (11) having a longitudinal direction and a lateral direction crossing each other; and a pair of leakage prevention walls (50) which are provided on both sides in the lateral direction of the absorber (11) and are composed of sheet members (50s) having a plurality of first welding parts (61) on the surface. The leakage prevention walls (50) have a lamination part (50L) where the sheet members (50s) are layered in a thickness direction in the way that it grips elastic members (52) stretching in the longitudinal direction. At least in a part of an area of the lamination part (50L), there are provided a plurality of second welding parts (62) bonding laminated sheet members (50s) to each other. An area of the second welding parts (62) is smaller than an area of the first welding parts (61).SELECTED DRAWING: Figure 5【課題】防漏壁を有する吸収性物品において、肌触りの悪化を抑制する。【解決手段】互いに交差する長手方向と横方向とを有する吸収体(11)と、前記吸収体(11)の前記横方向の両側に設けられ、表面に複数の第1溶着部(61)を有するシート部材(50s)からなる一対の防漏壁(50)と、を有し、前記防漏壁(50)は、前記長手方向に伸縮する弾性部材(52)を挟み込むようにして前記シート部材(50s)が厚さ方向に積層された積層部(50L)を有し、前記積層部(50L)の少なくとも一部の領域には、積層された前記シート部材(50s)を互いに接合する第2溶着部(62)が複数設けられており、前記第2溶着部(62)の面積は、前記第1溶着部(61)の面積よりも小さい。【選択図】図5
