Provided are a bodily fluid absorbent article improved to absorb bodily fluids quickly and a method for making a core for the bodily fluid absorbent article. A bodily fluid absorbent core 40 for a bodily fluid absorbent article is formed with one or more elongated depressions 43. The core 40 includes one or more surface layers 105 and one or more inner sections 105 lying inside the one or more surface layers 105. The one or more surface layers 105 are formed primarily of liquid-absorbent fibers and the one or more inner sections 106 are formed of the liquid-absorbent fibers and superabsorbent polymer particles.本發明之課題，係在提供可快速吸收體液之體液吸收性物品、及使用於其之芯的製造方法。本發明之解決手段，係於體液吸收性物品所使用之體液吸收性的芯(40)，形成凹部(43)。芯(40)，其係具有區隔凹部(43)之周壁(43a)之表層部分(105)、及位於比表層部分(105)更為內側之內側部分(106)。表層部分(105)，主要係由吸水性纖維所形成，內側部分(106)，則係由處於混合狀態之吸水性纖維及高吸水性聚合物粒子所形成。
