Description

溝７１についてより具体的に説明すると、溝７１は、吸収コア３１の非肌当接面側から肌当接面側に向かって窪んだ凹部となっている。つまりこの部分は、吸収コア３１の構成材料が配されない空間部分となっている。空間部分である溝７１によって区画された吸収コア３１の部分は、相対的に非肌当接面側に突出し、複数が独立して整列配置された、突出吸収部８１とも言うべき構造となっている。また、液吸収層３を厚み方向に見て、溝７１の肌当接面側の上部は吸収コア３１の一部として凹部吸収部７２となっている。凹部吸収部７２は、溝７１の空間の分だけ小吸収部８よりも厚みが薄く、肌当接面側へと偏在している。このため、離間部７は隣接する小吸収部８よりも坪量が小さくなっている。また、小吸収部８は突出吸収部８１とこれと厚み方向に連続する連続層６の部分を含む構成となっている。したがって、凹部吸収部７２と小吸収部８とは、液吸収層３の肌当接面側で連続層６となって平坦面を形成する（図２（Ａ）参照）。 The groove 71 will be described more specifically. The groove 71 is a recess that is recessed from the non-skin contact surface side of the absorbent core 31 toward the skin contact surface side. That is, this portion is a space portion where the constituent material of the absorbent core 31 is not disposed. The portion of the absorbent core 31 partitioned by the groove 71 that is a space portion has a structure that can also be referred to as a protruding absorption portion 81 that protrudes relatively to the non-skin contact surface side, and a plurality of them are independently aligned and arranged. Yes. Further, when the liquid absorbing layer 3 is viewed in the thickness direction, the upper part of the groove 71 on the skin contact surface side is a recessed portion absorbing portion 72 as a part of the absorbing core 31. The recessed portion absorbing portion 72 is thinner than the small absorbing portion 8 by the space of the groove 71 and is unevenly distributed toward the skin contact surface side. For this reason, the spacing portion 7 has a smaller basis weight than the adjacent small absorbing portion 8. Moreover, the small absorption part 8 is a structure including the protrusion absorption part 81 and the part of the continuous layer 6 continuous with this in the thickness direction. Therefore, the recessed part absorption part 72 and the small absorption part 8 become the continuous layer 6 in the skin contact surface side of the liquid absorption layer 3, and form a flat surface (refer FIG. 2 (A)).

Claims
