PROBLEM TO BE SOLVED: To provide an absorbent article which efficiently exhibits an improvement effect of absorption performance by a hemagglutination agent, and excellent in absorption speed and absorption amount of menstrual blood.SOLUTION: An absorbent article 1 for absorbing menstrual blood comprises: a liquid permeable surface sheet 2; a liquid impermeable rear surface sheet 3; and an absorber 4 arranged between both sheets, and comprises a vertical direction X along a cross direction of a wearer and a lateral direction Y orthogonal to the vertical direction. The absorber 4 has flocculant arrangement parts 9 on which, a hemagglutination agent is arranged, on portions other than an excretion spot part P in plan view of the absorbent article. The respective flocculant arrangement parts 9 are preferably formed on a formation portion of a leakage prevention groove 81 extending in the vertical direction, on each of both sides sandwiching the excretion spot part P.SELECTED DRAWING: Figure 1【課題】血球凝集剤による吸収性能の向上効果が効果的に発現され、経血の吸収速度及び経血の吸収量に共に優れる吸収性物品を提供すること。【解決手段】吸収性物品1は、液透過性の表面シート2、液不透過性の裏面シート3及びこれら両シート間に配された配置された吸収体4を備え、着用者の前後方向に沿う縦方向X及び該縦方向に直交する横方向Yを備えた経血吸収用の吸収性物品であり、吸収体4は、吸収性物品の平面視における排泄スポット部P以外の部位に、血球凝集剤が配された凝集剤配置部9を備えている。凝集剤配置部9は、好ましくは、排泄スポット部Pを挟む両側それぞれにおいて縦方向Yに延びる防漏溝81の形成部位に形成されている【選択図】図1
