No embossed line is provided . It is effective to set the length of the pair of first embossed lines to 3/6 to 5/6 of the entire length of the absorber, and to separate these widthwise arrangements from each other by 4/7 to 6/7 of the entire width of the absorber. . Further, the shortest distance between the pair of second embossed lines is set to the total length of the absorber.
2/5 or less, and set the length in the width direction to 4/7 of the full width of the absorber.
Up to 6/7 is also effective. In addition, the longest interval between the pair of third embossed lines is set to 3/6 to 5/6 of the entire length of the absorber,
It is also effective to set the length in the width direction to 4/7 to 6/7 of the entire width of the absorber.

(1) It has been found that the provision of the second embossed lines (2) and (2) and the third embossed lines (3) and (3) is effective in preventing the entire absorber from being deformed.

くは約 4/7である。The first embossing line provided in the longitudinal direction is effective for preventing the above-mentioned mold collapse, improving the absorption rate by diffusing the liquid in the longitudinal direction, and improving the fit.
The length (L 1 ) is set to 3/6 to 5/6 of the total length of the absorber (L). If the length is less than 3/6, the fixing effect is small, so that the shape is easily deformed. If it exceeds, the absorbed body fluid may leak from both ends in the longitudinal direction. The preferred length is about 4/6 of the overall length (L) of the absorber. Further, the distance between the first emboss lines (W 1 )
Is set to 4/7 to 6/7 of the entire width (W) of the absorber, because the shape is likely to be lost outside this range, and is preferably about 4/7.

向の長さは吸収対全幅の約 4/7が良好である。The second embossing line provided in the center in the width direction promotes the diffusion of the body fluid in the width direction while improving the shape of the body fluid, thereby improving the absorption rate, and at the same time, in the region surrounded by the first embossing line. The minimum spacing (L 2 ) between the convex portions of the pair of second embossed lines is set to 2/5 or less of the overall length (L) of the absorber, and the width in the width direction is further reduced. Length (W 2 ) is the overall width of the absorber (W)
The reason for setting 4/7 to 6/7 is that the effect of preventing the shape collapse is reduced even if it is out of any range. Preferably, the shortest interval is about 1/10 of the total length of the absorber, and the length in the width direction is about 4/7 of the overall width of the absorber.

4/6及び 4/7がよい。Also, the third embossed lines at both ends in the longitudinal direction of the absorber also prevent the mold from being lost and improve the absorption speed by diffusing the body fluid in the width direction, and at the same time, the area surrounded by the first embossed line and the second embossed line. To prevent the body fluid absorbed into the body from leaking out of the absorber.
The longest interval (L 3 ) between the concave portions of the pair of third embossed lines is set to 3/6 to 5/6 of the entire length (L) of the absorber, and the length (W 3 ) in the width direction is absorbed. Body full width (W)
The reason for setting 4/7 to 6/7 is that if any of them is out of the range, it is impossible to prevent the mold from breaking down.
4/6 and 4/7 are good.
