Provided is a disposable diaper, in which fastening tapes are brought into direct engagement with the surface of an outer-face back sheet made of a nonwoven fabric. The disposable diaper is enabled to adjust its size slightly according to the body shape of a baby, by improving the force of the fastening tapes to engage with the outer-face back sheet and the force to join the outer-face back sheet and a leakage-preventing sheet. The disposable diaper has its outer-face back sheet made of a nonwoven fabric prepared by an air-through method, in which fibers are thermally melted to each other at the time of manufacturing the nonwoven fabric by feeding hot air in a drum transfer process. This nonwoven fabric is arranged to have the aforementioned drum contacting face side on the inner face side of the diaper and the drum noncontact face side on the outer face side of the diaper, or the outer face side of the aforementioned outer-face back sheet is subjected to a raising treatment over a predetermined rangeset as at least the engaging range of the aforementioned fastening tapes. As a result, the engaging force of the fastening tapes can be improved, and at least the aforementioned front-side end flap portion EFcan be longitudinally folded back at an arbitrary position.

An absorbent article including a fiber aggregate formed by opening the tow, a super absorbent polymer particle, and a sheet covering these components. The super absorbent polymer particle are bonded to the sheet with an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface at least at the portion to be provided with the super absorbent polymer particle in this sheet.

Absorbent article

An Absorber and an absorbent article including a fiber aggregate wherein a tow composed of fibers is used as the fiber aggregate, and the compression resilience RC is 45 to 60%. Also, the fiber aggregate has a density of 0.0075 g/cmor less, weight of 0.0075 g/cmor less and a mass of 1 to 15 grams.

Absorber and absorbent article

A shuffling hand feeling and unwanted non-uniform absorption characteristics in the case of using a tow (fiber bundle) are prevented. An absorbent body includes a fiber aggregateformed by opening the tow, a super absorbent polymer, and a sheet covering these components; and includes the super absorbent polymerbonded to the sheetwith an adhesive that is applied in a continuous plane to the entire surface or the substantially entire surface of at least the portion to be provided with the super absorbent polymerin this sheet
