PROBLEM TO BE SOLVED: To provide an absorbent article which is excellent in fitness to a body shape even when worn in a little misaligned state, and therefore hardly generates a gap between the article and a wearers skin and prevents liquid flow flowing on the surface of the skin side sheet, and can exhibit sufficient absorption performance.SOLUTION: An absorbent article 1 according to the present invention comprises a skin-side sheet 2, a non-skin-side sheet 3, and an absorbent core 41 interposed between these sheets 2, 3. The absorbent core 41 comprises a middle region 41M between a first region 41F located on a front zone A side and a second region 41R located on a rear zone C side and is provided with a thick section 42 in the middle region 41M, the thick section being thicker than the first region 41F and the second region 41R. The thick section 42 has a maximum-width section where the lateral length of the absorbent core 41 is at a maximum. The skin-side sheet 2 includes flexible shafts KL that act as the origin of flexion of the skin-side sheet 2 at locations corresponding to a boundary section BL disposed on the periphery of the contour of the thick section 42 of the absorbent core 41.SELECTED DRAWING: Figure 8COPYRIGHT: (C)2018,JPO&INPIT【課題】多少ズレた状態で着用されても、身体形状へのフィット性に優れることで着用者の肌との間に隙間を生じ難く、肌側シートの表面を流れる液流れを防止し、十分な吸収性能が発現できる吸収性物品を提供すること。【解決手段】本発明の吸収性物品1は、肌側シート2、非肌側シート3と、これら両シート2,3間に介在された吸収性コア41とを備える。吸収性コア41は、前方区域A側に位置する第一領域41F及び後方区域C側に位置する第二領域41Rとの間に中間領域41Mを有し、中間領域41Mに第一領域41F及び第二領域41Rよりも厚みの厚い肉厚部42を備える。肉厚部42は、吸収性コア41の横方向における長さが最大となる最大幅部を有する。肌側シート2は、吸収性コア41における肉厚部42の輪郭周辺の位置に配される境界部BLに対応する位置において肌側シート2が屈曲される起因となる可撓軸KLを有する。【選択図】図8
