PROBLEM TO BE SOLVED: To provide an absorbent article in which a gap is hardly generated between an absorbent article and a skin, fitness is improved, a body fluid hardly flows on a skin, and leakage prevention property is improved.SOLUTION: An absorbent article 1 has an absorbent core 41. The absorbent core 41 is divided into a center core area CT and side core areas ST, ST in a lateral direction Y, and has a middle height part 43 protruded to a skin side relative to a skin facing surface ST1 of the side core area ST, on a skin facing surface side of an excretion part facing part B on the center core area CT. The absorbent core 41 has a non-skin side vertical groove part 5 arranged on a position overlapped to the vertical center line CL, and extends along a vertical direction X, on a non-skin facing surface side of the center core area CT. A basis weight of a part where the non-skin side vertical groove part 5 is formed by reducing a basis weight of a formation material of the absorbent core 41 relative to a basis weight ST1 of each side core area ST.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】着用中、吸収性物品と肌との間に隙間が生じ難く、フィット性が更に向上し、体液が肌を伝って流れ難く、防漏性が更に向上する吸収性物品を提供すること。【解決手段】吸収性物品1は吸収性コア41を有する。吸収性コア41は、横方向Yに中央コア領域CT及び側方コア領域ST,STに区分され、中央コア領域CTにおける排泄部対向部Bの肌対向面側に、側方コア領域STの肌対向面ST1よりも肌側に突出する中高部43を有する。吸収性コア41は、中央コア領域CTの非肌対向面側に、縦中心線CLと重なる位置に配され、且つ縦方向Xに沿って延びる非肌側縦溝部5を有する。非肌側縦溝部5が配された部分の坪量は、各側方コア領域STの坪量STwに比して吸収性コア41の形成材料の坪量を減らして形成されている。【選択図】図2
