To provide an absorbent article including a leak preventing layer comprising a nonwoven fabric enhanced in liquid leak prevention property without damaging softness.MEANS: In an absorbent article 10 comprising a surface layer 1, a leak preventing layer 2 and an absorber layer 3, the leak preventing layer 2 is directly laminated on the absorber layer 3. The leak preventing layer 2 has a melt-blown layer 41, and a protective layer 42 for the melt-blown layer 41, and has an embossment part in which both layers are joined, and a non-embossment part excluding the embossment part. The leak preventing layer 2 has a non-open hole area in the non-embossment part. The non-open hole area is an area in which a through hole penetrating into the thickness direction is not provided in an interfiber space including an area in which an area of a rectangular form E comprising diagonal lines E1, E1 of a length of 10 μm becomes 25 μmor more, when the leak preventing layer 2 is planarly viewed. The non-open hole area is arranged in an area in which the leak preventing layer 2 is overlapped on the absorber layer 3.SELECTED DRAWING: Figure 1 【課題】柔らかさを損なわずに液漏れ防止性を高めた不織布からなる防漏層を備える吸収性物品を提供する。【手段】表面層１、防漏層２、及び吸収層３を有する吸収性物品１０であって、防漏層２が吸収層３と直接積層されている。防漏層２は、メルトブローン層４１と該メルトブローン層４１の保護層４２とを有し、両層が接合されたエンボス部とエンボス部以外の非エンボス部とを有する。防漏層２は、非エンボス部において非開孔領域を有する。非開孔領域は、防漏層２を平面視したときに、対角線Ｅ１，Ｅ１の長さ１０μｍからなる長方形Ｅの面積が２５μｍ２以上となる領域を包含する繊維間空間が厚み方向に貫通する貫通孔、を有さない領域である。非開孔領域は、防漏層２が吸収層３と重なる領域に配されている。【選択図】図１
