When a large amount of liquid is excreted at one time by interposing the liquid permeable sheet 10 having such an uneven shape between the top sheet 2 and the absorber 4 or between the back sheet 3 and the absorber 4 Even
Since the liquid is temporarily held in the concave portion of the liquid permeable sheet 10,
Liquid flow in the plane direction is prevented, and liquid leakage is effectively prevented. Moreover, unlike the disposable diaper described in JP-A-6-70957 described above, the disposable diaper 1 of the present embodiment holds the liquid inside the diaper and controls the liquid flow. Return is also suppressed,
Liquid leakage is more effectively prevented.

Therefore, the recesses 11 are not communicated with each other and are arranged independently.
Further, each recess 11 is arranged so as to have a shape that divides a hexagon into six equal parts. That is, the six concave portions 11 are arranged so as to form one hexagon, and the hexagons are arranged so as to form a turtle pattern. The shape of the concave portion 11 formed in the liquid permeable sheet 10 is not limited to a triangle, but may be a circle (an enlarged sectional view of a main part is shown in FIG. 3B), a square, or another shape. In particular, when circular recesses are formed, the recesses do not necessarily have to be independent from each other.

る。In the embodiment shown in FIG. 5, the liquid-permeable sheet 10 is constituted by a laminate in which two sheets having irregularities are laminated. The laminated body has an uneven shape in its thickness direction, and is provided with a number of close contact portions 13 between two sheets to be integrated and forms a liquid holding space between the close contact portions. The contact portion 14 is provided. By using such a laminate, more space for holding the liquid excreted in the liquid permeable sheet 10 is formed than in the liquid permeable sheet shown in FIGS. 3 (a) and 3 (b). You. As a result, liquid leakage is more effectively prevented. In the present embodiment, the laminated body is configured by laminating two layers of sheets. However, instead of this, a laminated body of laminated three or more layers may be used. The laminate used in the present embodiment can be manufactured by, for example, a method described in column 11 line 13 to column 12 line 19 of JP-A-9-123325 filed by the present applicant.
