PROBLEM TO BE SOLVED: To provide an absorbent article including an absorbent body having a thin thickness before absorption, and even after absorption, does not inhibit super absorbent polymer (SAP) swelling, wherein deformation such as twisting is unlikely to occur.SOLUTION: The absorbent article has a liquid-permeable front surface sheet 2, a liquid impermeable rear surface sheet 3, and an absorbent body 6located between both the sheets. The absorbent body includes a super absorbent polymer-containing layer 4 and a non-woven fabric layer 5, and the non-woven fabric layer has regions 7 where the inter-fiber porosity is relatively large and regions 8 where the inter-fiber porosity is relatively small. The regions where the inter-fiber porosity is relatively large, have a larger number of fiber tips forming the non-woven fabric layer, relative to the regions where the inter-fiber porosity is relatively small, and the non-woven fabric layer has stretchability.COPYRIGHT: (C)2012,JPO&INPIT【課題】吸収前は薄型であり、吸収後も高吸水性樹脂(SAP)の膨潤を阻害せず、ヨレ等の変形も生じにくい吸収体を含む吸収性物品を提供する。【解決手段】本発明の吸収性物品は、液透過性表面シート2、液不透過性裏面シート3、およびこれら両シート間に位置する吸収体6を有し、吸収体が高吸水性樹脂含有層4と不織布層5から構成されており、不織布層に相対的に繊維間空隙率が大きい領域7と相対的に繊維間空隙率が小さい領域8があり、不織布層を構成する繊維の端部が相対的に繊維間空隙率が小さい領域よりも相対的に繊維間空隙率が大きい領域において多く、不織布層が伸張性を有する。【選択図】図1
