The superabsorbent polymer particles 1
Since No. 1 does not exist, the thickness of the region 13 is slightly increased or hardly increased compared to before the liquid absorption. As a result, in the absorber 4 after absorbing the liquid, the non-polymer-existing region 13 is relatively depressed as compared with other regions (that is, regions where the highly absorbent polymer particles 11 are present). , A groove 14 is formed. In the region of the absorber 4 where the superabsorbent polymer particles 11 are present, the swelling of the superabsorbent polymer particles 11 by liquid absorption has reduced the flexibility and flexibility before liquid absorption. In No. 14, since the superabsorbent polymer particles 11 are not present, the flexibility and flexibility before liquid absorption are almost maintained, or even if they are reduced, the degree of reduction is high. Is extremely small as compared with the region in which As a result, in the absorber 4 after absorbing the liquid, the groove 14 is more easily bent and deformed than in other regions. Moreover, the bent and deformed polymer non-existent region 13
Has a higher bending recovery property than other regions in the absorber 4. In other words, the groove 14, that is, the non-polymer-existing region 13 becomes a flexible axis of bending deformation, and the absorber 4
It can be easily bent along the polymer non-existing region 13. Therefore, in the diaper 1 of the present embodiment, the same good fit as before the liquid absorption is maintained after the liquid absorption, and the liquid leakage is effectively prevented.

In particular, it is preferably 3 to 10 mm. The width of the non-polymer-existing region 13 may be substantially uniform along its length direction, or the width of a portion of the absorber 4 that is particularly required to be bent may be increased, and the degree of the bent deformation of the portion may be increased. May be increased to further enhance the fit of the diaper 1 after absorbing the liquid.
