A nonwoven fabric for an absorbent article has a plurality of first ridges and a plurality of first grooves on a first surface, each of the first ridges extending in a first direction and being provided with a first top surface including a first top section and first side surfaces, and each of the first grooves extending in the first direction; each of the first grooves of the nonwoven fabric has a plurality of second ridges and a plurality of bottom sections on the first surface, each of the second grooves being contiguous with two adjacent first ridges among the plurality of first ridges and having a second top section; the nonwoven fabric is provided with a plurality of predetermined recess units; and in each of the plurality of recess units, the fiber density of the first surface is lower than the fiber density of the first top surface.

Nonwoven fabric for absorbent article

The present invention addresses the problem of providing an absorbent article in which a bonding part for bonding a liquid-permeable layer to an absorbent core has been formed in a low-basis-weight region of the absorbent core and which has all of sufficient flexural rigidity of the bonding part, sufficient bonding strength of the bonding part, and sufficient liquid-absorbing properties. This problem is solved with an absorbent core which comprises a first region that has a given absorbent-material basis weight and second regions (regions) that have a lower absorbent-material basis weight than the first region, wherein the ratio of the basis weight of a highly absorbing polymer to the basis weight of the absorbent material in the second regions is regulated to 10/100 to 47/100, and compressed parts are formed inside the second regions.
