Abstract: A compressed portion is formed in the absorbent article by compressing the absorber through a compression process. The compressed portion has a top-surface groove formed on the skin-contact-surface side, and a back-surface groove formed on the clothing-contact-surface side. A bottom portion of the top-surface groove is flat. Since the recessed portions are formed in the bottom portion of the back-surface groove through the compression process, a compression part where the density of the absorber is increased more than in an uncompressed portion and high compression parts where the density of the absorber is increased more than in the compression part are formed in the bottom portion. Thus, the absorbent article can be permeate into by a thick liquid, and is more likely to absorb liquid.

Abstract: An absorbent article that includes a water-disintegratable top sheet, a water-disintegratable back sheet, and a water-disintegratable absorber interposed between the top sheet and the back sheet. Adhesive coating regions of an adhesive are formed in the back sheet, and the coating regions of the adhesive are provided to continuously extend from one face of the back sheet to the other face of the back sheet.

Abstract: An absorbent article according to the present invention includes: a water-decomposable top sheet, a water-decomposable back sheet; and a water-decomposable absorber placed between the top sheet and the back sheet. The back sheet is formed of multiple sheet pieces each being smaller than a main body of the absorbent article, and each sheet piece at least partially overlapping adjacent one or more of the other sheet pieces. In addition, an adhesive is applied to each overlapping region where adjacent two of the sheet pieces overlap each other.

Abstract: Disclosed is a wrapping sheet for an absorbent article including an absorbent exhibiting at least a fluid-retaining property, the wrapping sheet includes: a first fiber layer formed by application of a high-pressure water jetting treatment, the first fiber layer including pulp fiber and chemical fiber, the pulp fiber content of the first fiber layer being 30% by mass to 70% by mass, the chemical fiber content of the first fiber layer being 70% by mass to 30% by mass, and the average fiber length of the chemical fiber being 20 mm or less; and a second fiber layer arranged by laminating the second fiber layer to the first fiber layer, the pulp fiber content of the second fiber layer being 70% by mass to 100% by mass.
