PROBLEM TO BE SOLVED: To provide an absorbent article, an absorbent core of which is fitted to a wearers body to hardly cause liquid leakage.SOLUTION: An absorbent article 1 includes: an absorbent core and a pair of three-dimensional leakage preventing structure. A front area A and a rear area B of the absorbent core 4 are respectively provided with deformation guide parts N1, N2 recessed from side edges S1, S2 inwardly in the width direction and inwardly in the longitudinal direction. The three-dimensional leakage preventing structure 8 has a base end part 8a and a free end part 8b, and the base end part 8a is located on the absorbent core 4 in the skin opposite surface. In the front and rear end part areas in the longitudinal direction Y in the three-dimensional leakage preventing structure 8, the position J for fixing the free end part 8b of the three-dimensional leakage preventing structure 8 is located between the end edges T1, T2 and the deformation guide parts N1, N2, and also between the side edges S1, S2 and the inward end Q in the width direction of the deformation guide parts N1, N2.COPYRIGHT: (C)2014,JPO&INPIT【課題】吸収性コアが着用者の身体にフィットし、液漏れが起こりにくい吸収性物品を提供すること。【解決手段】吸収性物品1は、吸収性コア及び一対の立体防漏構造を備える。吸収性コア4の前方域A及び後方域Bに、側縁S1,S2から幅方向内方及び長手方向内方に向かって入り込んだ変形誘導部N1,N2を設ける。立体防漏構造8は基端部8a及び自由端部8bを有し、かつ基端部8aが肌対向面における吸収性コア4上にある。立体防漏構造8における長手方向Yの前後端部域において該立体防漏構造8の自由端部8bを固定する位置Jが、端縁T1,T2と変形誘導部N1,N2の間であって、かつ側縁S1,S2と変形誘導部N1,N2の幅方向の内方端Qとの間にある。【選択図】図3
