PROBLEM TO BE SOLVED: To provide an absorbent article capable of improving absorption capacity of an excreted liquid while securing an ability to diffuse the excreted liquid on a liquid diffusion sheet repeatedly and utilizing a whole absorber effectively.SOLUTION: A liquid permeable sheet 11 has a plurality of protrusion parts 11a rising on a surface of an opposite side to an absorber 4 of the liquid permeable sheet 11 in a direction opposite to the absorber 4, and a plurality of recesses 11b provided between the adjacent protrusion parts 11a and 11a. A liquid diffusion sheet 13 extending to a longer direction of the absorber 4 is disposed between the absorber 4 and a liquid impermeable sheet. The liquid diffusion sheet 13 has transpiration parts 20 and 21 for transpiring moisture contained in the liquid diffusion sheet 13 to the outside on at least one end side of the longer direction of the liquid diffusion sheet 13, which extends to the outer side of the absorber 4 from an end part of the longer direction of the absorber 4.COPYRIGHT: (C)2015,JPO&INPIT【課題】液拡散シートにおける排泄液を繰り返し拡散させる能力を確保して、吸収体全体を有効に活用して排泄液の吸収能力を向上させることができる吸収性物品を得る。【解決手段】液透過性シート11を、該液透過性シート11における前記吸収体4とは反対側の面に、該吸収体4とは反対側の方向に立ち上がる複数の隆起部11aと、隣り合う隆起部11a,11aの間に設けられた複数の凹部11bとを有していると共に、前記吸収体4と液不透過性シート13との間に、該吸収体4の長手方向に延びる液拡散シート13を配設し、該液拡散シート13を、該液拡散シート13の長手方向の少なくとも一端側に、前記吸収体4の長手方向の端部より該吸収体4の外方側に延びて、液拡散シート13に含まれている水分を外部に蒸散させる蒸散部20,21を備えた構成とする。【選択図】図3
