To provide an absorbent article to which inappropriate deformation is unlikely to occur.SOLUTION: An absorbent article is provided with an absorbent core. The absorbent core has a front core part and a rear core part positioned on both end parts side in the back and forth direction and an intermediate core part positioned between the front core part and the rear core part. The absorbent core has a boundary part positioned between the intermediate core part and the rear core part and crossing the absorbent core in the width direction orthogonal to the back and forth direction. The boundary part is provided with a boundary groove part extending continuously or non-continuously in the width direction and a small absorption part having greater basis weight than the boundary groove part. The intermediate core part and the rear core part are provided with an area of greater basis weight than the boundary groove part.SELECTED DRAWING: Figure 3【課題】不適切な変形が生じにくい吸収性物品に関する。【解決手段】吸収性物品は、吸収性コアを具備する。上記吸収性コアは、前後方向の両端部側に位置する前方コア部及び後方コア部と、上記前方コア部及び上記後方コア部の間に位置する中間コア部とを有する。上記吸収性コアは、上記中間コア部と上記後方コア部との間に位置し、上記前後方向と直交する幅方向で上記吸収性コアを横切る境界部を有する。上記境界部には、上記幅方向に連続又は非連続に延びる境界溝部と、上記境界溝部よりも高い坪量を有する小吸収部が設けられる。上記中間コア部及び上記後方コア部には、上記境界溝部よりも坪量の高い領域が設けられる。【選択図】図３
