The object of the present invention is to widely diffuse urine in the absorbent body through easily flowing the urine to the front and back ends of a groove. An absorbent article has a slot- or slit-shaped groove on the surface of a liquid permeable sheet with an area covering the range for discharge of urine along the longitudinal direction of the incontinence pad. The groove of the absorbent article stated above respectively forms an area with a tapering end on both sides. The length of the area with the tapering end stated above is respectively formed longer than 20% of the full length of the absorbent body. The momentum of the urine can be controlled in help of the urine easily flowing to the end of the absorbent article because the cross-section of the flow path becomes gradually smaller in the area with the tapering end. Therefore, with the increase of the contact area of the inner surface of the absorbent article, the urine is draw through the capillarity effect and stores in the absorbent article.本發明的課題在於透過使尿容易流動至凹槽的前後端部而能夠使尿在吸收體的整體擴散。吸收性物品在透液性表面片材側的面的包括尿排出部位的範圍,沿失禁墊的長度方向具備凹槽狀或狹縫狀的吸收體凹部。上述吸收體凹部的長度方向兩端部分別形成為寬度朝向端部側逐漸變窄之尖頭形狀的寬度逐漸減小區間,上述寬度逐漸減小區間分別相對於吸收體凹部的全長以20%以上的長度形成。在上述寬度逐漸減小區間中,流路的截面積逐漸減小,因此能夠抑制尿的流動勢頭下降,從而使得尿容易流動至吸收體凹部的端部。因此,與吸收體凹部的內表面接觸的面積增加,透過毛細管現象引入尿並將其吸收保持於吸收體內。4‧‧‧吸收體4c‧‧‧吸收體的前端4d‧‧‧吸收體的後端20‧‧‧吸收凹部20a‧‧‧收體凹部的前端20b‧‧‧收體凹部的後端23‧‧‧寬度逐漸減小區間23A‧‧‧前側寬度逐漸減小區間23B‧‧‧後側寬度逐漸減小區間A、B‧‧‧分離距離C‧‧‧吸收體的全長L‧‧‧吸收體凹部的全長P‧‧‧吸收體凹部的最大寬度
