PROBLEM TO BE SOLVED: To provide an absorbent article which improves fitness by improving generation of distortion and wrinkles in an absorbent core when worn and can suppress liquid flow.SOLUTION: In an absorbent core 24, a plurality of recesses 4A to 4C are formed in a scattered state in a vertical direction X and a horizontal direction Y is formed in a core back part 24B to be positioned at the back of a central position of an absorbent article in a vertical direction, a central recess area 55 having a plurality of recesses 4A are formed in a central part in the horizontal direction Y of the core back part 24B, and lateral recess areas 56 having a plurality of recesses 4B are formed on both sides having the central recess areas 55 in between respectively. An aspect ratio to be a value after dividing length in the vertical direction X of the recesses 4A, 4B by length in the horizontal direction Y is closer to 1.0 in the central recess area 55 than the lateral recess area 56, and areas of the recesses 4A, 4B are larger in the central recess area 55 than the lateral recess area 56.SELECTED DRAWING: Figure 5【課題】着用時の吸収性コアにおける歪み及びしわの発生を改善してフィット性を向上させると共に、液流れの発生を抑制し得る吸収性物品を提供すること。【解決手段】吸収性コア24には、縦方向における前記吸収性物品の中央位置より後方に位置するコア後部24Bに、縦方向X及び横方向Yに分散した状態に複数の凹部4A~4Cが形成されており、コア後部24Bの横方向Yの中央部に、凹部4Aを複数有する中央凹部領域55が形成され、該中央凹部領域55を挟む両側それぞれに、凹部4Bを複数有する側方凹部領域56が形成されており、凹部4A、4Bの縦方向Xの長さを横方向Yの長さで除した値である縦横比は、側方凹部領域56よりも中央凹部領域55の方が1.0に近く、凹部4A,4Bの面積は、側方凹部領域56よりも中央凹部領域55の方が大きい。【選択図】図5
