An absorbent article 10 includes a liquid permeable surface layer 11, a leakage preventive layer 12, and an absorbent layer 13, and has a longitudinal direction Y and a width direction X orthogonal thereto. At both left and right edges 17 along the longitudinal direction Y, the article 10 includes necked portions 15 and 16 dividing the article 10 into a front portion A, a central portion C, and a rear portion B along the longitudinal direction Y. Maximum widths of the front portion A and the rear portion B are nearly the same, and a maximum width of the central portion C is smaller than the maximum widths of the front portion A and the rear portion B. The central portion C is provided with leakage preventive grooves 20 projected in an arc shape outward the width direction formed to nearly match a shape of both left and right edges 17C at positions inside in the width direction of both the left and right edges 17C in the central portion C.本創作之吸收性物品10包括液體透過性表面層11、防漏層12及吸收層13,且具有長度方向Y及與其正交之寬度方向X。物品10於沿長度方向Y之左右兩側緣17具有將該物品10沿長度方向Y而劃分為前方部A、中央部C及後方部B之內縮部15、16。前方部A及後方部B其等之最大寬度大致相同,並且中央部C之最大寬度較前方部A及後方部B之最大寬度窄。於中央部C,於較該中央部C之左右兩側緣17C更靠寬度方向內側之位置上,以大致仿照該左右兩側緣17C之形狀之方式而形成有呈朝該寬度方向之外側凸出之弧狀之防漏槽20。10‧‧‧衛生護墊11‧‧‧表面層12‧‧‧防漏層13‧‧‧吸收層13A‧‧‧前方部A側之端緣13B‧‧‧後方部B側之端緣14‧‧‧周緣接合部15‧‧‧前方內縮部16‧‧‧後方內縮部17‧‧‧側緣17A‧‧‧側緣17B‧‧‧側緣17C‧‧‧側緣18A‧‧‧前端緣18B‧‧‧後端緣19‧‧‧點狀擠壓部20‧‧‧第1防漏槽21A‧‧‧第2防漏槽21B‧‧‧第2防漏槽22‧‧‧前方部第1防漏槽22A‧‧‧內側分支部22B‧‧‧外側分支部23‧‧‧後方部第1防漏槽23A‧‧‧內側分支部23B‧‧‧外側分支部24‧‧‧第1擠壓部25‧‧‧第2擠壓部26‧‧‧前方部第2防漏槽26A‧‧‧內側分支部27‧‧‧後方部第2防漏槽27A‧‧‧內側分支部28‧‧‧第3擠壓部29‧‧‧第4擠壓部A‧‧‧前方部A1‧‧‧最大寬度部A2‧‧‧長度方向前端部B‧‧‧後方部B1‧‧‧最大寬度部B2‧‧‧長度方向前端部C‧‧‧中央部C1‧‧‧最大寬度部X‧‧‧寬度方向Y‧‧‧長度方向
