PROBLEM TO BE SOLVED: To provide an absorbent article having excellent fittability at both cases of before absorbing liquid and after having absorbed the liquid, and having excellent re-wetting properties and wearing properties.SOLUTION: The absorbent article includes an absorber 7 including a longitudinal direction LO, a lateral direction LA, and a thickness direction. The absorber 7 includes one surface and the other surface, an absorbent core 9, and a core wrap 11. The absorbent core 9 includes groove parts 18 with bottom parts, recessed from the one surface in the thickness direction. Each groove part 18 includes a main groove part 19 extending in the longitudinal direction, and a plurality of sub grooves 21 that extends in a direction crossing with the longitudinal direction, with the main groove part 19 defined as a base end 24, and has a terminal end 25. A basis weight of a part of the absorbent core 9 that forms bottom parts of the main groove 19 and the sub groove parts 21 and extends in the thickness direction is smaller than an average basis weight of the absorbent core 9. The main groove part 19 is joined with the core wrap 11 at the bottom part 20, and the sub groove part 21 connected to the main groove part 19 at the base end 24 via the core wrap 11. The absorbent core 9 is present at the tip of the terminal end 25.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】液体を吸収する前及び液体を吸収した後の両方におけるフィット性、リウェット性に優れ、着用感に優れる吸収性物品を提供すること。【解決手段】長手方向LO、短手方向LA及び厚さ方向を有する吸収体7を含む吸収性物品であって、吸収体7は、一方の面及び他方の面を有し、吸収コア9と、コアラップ11とを備え、吸収コア9は、一方の面から厚さ方向に窪んだ底部を有する溝部18を備え、溝部18が長手方向に延びる主溝部19と、主溝部19を基端24として長手方向と交差する方向に延び、終端25を有する複数の従溝部21とを備え、主溝部19及び従溝部21のそれぞれの底部を形成し且つ厚さ方向に延在する部分の吸収コア9の坪量は、吸収コア9の平均坪量よりも小さく、主溝部19は、底部20にコアラップ11が接合されており、従溝部21は、コアラップ11を介して主溝部19と基端24で連結され、終端25の先に吸収コア9が存在する。【選択図】図2
