To provide an absorbent article which is high in diffusibility of liquid and can effectively absorb urine by SAP.SOLUTION: In an absorbent article provided with an upper layer absorber 30 and a lower layer absorber 40 that are layered in a thickness direction between a liquid-permeable top sheet 10 and a liquid-impermeable back sheet 20, the upper layer absorber 30 has an upper side opening 31, and the lower layer absorber 40 has a lower side opening 41 that extends in a longitudinal direction and overlaps at least partially the upper side opening 31. Between the upper layer absorber 30 and the lower layer absorber 40 is provided a SAP layer 50 formed by a plurality of superabsorbent polymers (SAP) being arranged. The SAP layer 50 is formed on both left and right sides in a width direction of an opening penetration part 42 where at least the upper side opening 31 and the lower side opening 41 overlap.SELECTED DRAWING: Figure 2【課題】液体の拡散性が高くＳＡＰによって効果的に尿を吸収できる吸収性物品を提供する。【解決手段】液透過性のトップシート１０と液不透過性のバックシート２０の間に介在して厚み方向に重ねられた上層吸収体３０と下層吸収体４０とを備えた吸収性物品において，上層吸収体３０は上側開口部３１を有し，下層吸収体４０は長手方向に延び上側開口部３１と少なくとも部分的に重なる下側開口部４１を有しており，上層吸収体３０と下層吸収体４０の間には，複数の高吸水性ポリマー（ＳＡＰ）が配置されることにより形成されたＳＡＰ層５０が設けられ，ＳＡＰ層５０は，少なくとも上側開口部３１と下側開口部４１とが重なる開口貫通部分４２の幅方向の左右両側に形成されている。【選択図】図２
