Is provided with a pair of outer embossing lines extending longitudinally along the side edge and being open at the front and rear sides of the longitudinal direction along the side edge, respectively, and further inside these convex curved lines. Extending along the longitudinal direction
By providing a pair of inner embossed lines that are opened later , the absorption in the longitudinal direction is promoted and the fit is improved. At this time, the length of the pair of outer embossed lines is set to 3 /
6 to 5/6, and these arrangements in the width direction are separated from each other by 4/7 to 6/7 of the entire width of the absorber, and the length of a pair of inner embossed lines is set to 3/6 of the total length of the absorber. 55/6, and the shortest distance between the convex portions is the distance between the pair of outer embossed lines.
It is effective to set 1/6 to 5/6.

The outer embossing line (1) (1) the length of (L 1) from was 3/6 to 5/6 of the absorbent body overall length (L) is
If it exceeds 5/6, leakage of urine and the like in the waist direction of the absorber (4) occurs, while if it is less than 3/6, the fixing effect is small, so that the shape collapse cannot be effectively prevented. The preferred length is about 4/6 of the total length (L). Also, the interval (W) between these outer embossing lines (1) and (1)
1 ) was set to 4/7 to 6/7 of the full width (W) of the absorber.
If it exceeds / 7, the effect of preventing shape collapse will be reduced, and if it is less than 4/7, the distance between the embossed lines on both sides will be too narrow, and the absorber will feel hard. A preferable interval is about 4/7 of the entire width (W).

This is to prevent the shape from being lost. The length (L 2 ) of the inner embossed lines (2) and (2) is determined by the total length of the absorber (L).
The reason for 3/6 to 5/6 is the same as the reason for limiting the outer embossed line, because if it exceeds 5/6, leakage of urine etc. from the waist direction will occur, and if it is less than 3/6, it will lose its shape. . The preferred length is about 4/6 of the total length (L). The shortest distance (W 2 ) between the convex portions of the inner emboss lines (2) and (2) is set to 1/6 to 5/6 of the mutual distance (W 1 ) of the outer emboss lines (1) and (1). Is the same as the reason for limiting the outer embossed line.
If the value exceeds / 6, the effect of preventing shape collapse is small, and if it is less than 1/6, the absorber becomes hard. The preferred shortest interval is about the outer emboss line interval (W 1 ).
2/6 is good.
