The present invention addresses the problem of increasing the absorbent capacity, liquid diffusibility, and collecting capacity of an absorbent article having a multilayered absorber. This absorbent article is provided with a liquid-permeable top sheet (10) located on the skin-facing-surface side, a liquid-impermeable back sheet (20) located on the non-skin-facing-surface side, and a plurality of absorbers stacked in the direction of thickness between the top sheet (10) and the back sheet (20). The plurality of absorbers includes at least an upper-layer absorber (30) located on the top-sheet (10) side and a lower-layer absorber (40) located on the back-sheet (20) side. The upper-layer absorber (30) has an upper opening (31) having a prescribed length and width, the upper opening (31) extending in the longitudinal direction, and the lower-layer absorber (40) has a lower opening (41) having a shorter length and width than the upper opening (31), the lower opening (41) extending in the longitudinal direction. The upper opening (31) and lower opening (41) at least partially overlap in the direction of thickness.本發明係提高具有複數層吸收體的吸收性物品的吸收能力、液擴散性及收集能力。吸收性物品具備:透液性的頂片10,位於皮膚對向面側;不透液性的背片20,位於皮膚非對向面側;及複數個吸收體,介於頂片10與背片20之間,重疊於厚度方向上。複數個吸收體至少包含位於頂片10側的上層吸收體30及位於背片20側的下層吸收體40。上層吸收體30具有沿著長度方向延伸而有預定長度及寬度的上側開口部31,下層吸收體40具有沿著長度方向延伸而有比上側開口部31短的長度及寬度的下側開口部41。上側開口部31與下側開口部41於厚度方向上至少部分重疊。10‧‧‧頂片20‧‧‧背片30‧‧‧上層吸收體31‧‧‧上側開口部32‧‧‧延伸部40‧‧‧下層吸收體/第一下層吸收體41‧‧‧下側開口部/第一下側開口部50‧‧‧SAP層61‧‧‧第一擴散片62‧‧‧第二擴散片63‧‧‧第三擴散片/液擴散性片100‧‧‧吸收性物品W1‧‧‧寬度W2‧‧‧寬度
