PROBLEM TO BE SOLVED: To increase an absorption speed by quickly absorbing body fluid to an absorber side from a surface side and to make it hard for the body fluid to backflow onto the surface sheet side without causing spilling of polymer particles or the like or degradation of the touch to the skin.SOLUTION: In a sanitary towel 1 where an absorber 4 is mediated between a liquid-permeable surface sheet 3 and a non liquid-permeable rear surface sheet 2, many open holes 10, 10... that go from a skin surface side of the liquid-permeable surface sheet 3 through to a non-skin surface side of the absorber 4 are formed. The open holes 10 are formed in the way that an opening area on the non-skin side is larger than an open hole area on the skin side. The liquid-permeable surface sheet 3 has projection edge parts 11 projecting to the absorber 4 side from a base surface of the liquid-permeable surface sheet 3 along a peripheral edge of the open holes 10, and the projection edge parts 11 are disposed along inner surfaces of the open hole 10 of the absorber 4.COPYRIGHT: (C)2015,JPO&INPIT【課題】ポリマー粒子などのこぼれや肌触りの悪化を招くことなく、体液を表面シートから吸収体側に素早く引き込んで吸収スピードを速めるとともに、表面シート側への逆戻りを生じにくくする。【解決手段】透液性表面シート3と不透液性裏面シート2との間に吸収体4が介在された生理用ナプキン1において、前記透液性表面シート3の肌面側から吸収体4の非肌面側にかけて貫通する多数の開孔10、10…を形成する。前記開孔10は、非肌側の開口面積が肌側の開孔面積より大きく形成する。前記透液性表面シート3は、開孔10の周縁に沿って該透液性表面シート3の基面から前記吸収体4側に突出する突出縁部11を有するとともに、前記突出縁部11が前記吸収体4の開孔10内面に沿って配設されるようにする。【選択図】図3
