Abstract: In an absorbent product, an absorbent core includes an upper absorber including a super absorbent material fixedly attached between upper and lower absorber sheets. The upper absorber includes material existence regions that are arranged in the width direction and to which the super absorbent material is fixedly attached, and a material non-existence region in which the super absorbent material does not exist is arranged between each pair of adjacent material existence regions.

Abstract: Absorbent article suppressing occurrence of malodor after use while preventing a rash on a wearer's skin. The absorbent article includes an absorbent body, and a fumaric acid-supported sheet disposed on a skin surface side of the absorbent body. The fumaric acid-supported sheet is a sheet which supports fumaric acid particles having an average particle diameter of 30 ?m or less, and/or a sheet in which at least a part of constituent fibers is coated with fumaric acid. When being in contact with the body fluid or the like, fumaric acid is not immediately but slowly dissolved so that alkalization at the area around fumaric acid can be prevented over a long period of time. In addition, fumaric acid has an action of inhibiting proliferation of putrefactive bacteria and, therefore, can prevent occurrence of malodor from the absorbent article having absorbed the body fluid or the like.

Abstract: An absorbent sheet manufacturing apparatus has a particle collision surface (224) that extends downward from a cylinder outer surface (211) in between the lowermost part of a supply cylinder (21) and a second sheet conveying roller (41). Some of the particles emitted forward in the rotation direction of the supply cylinder (21) from recessed supply portions (212) that have passed a first cover part (221) collide with the particle collision surface (224), and the colliding particles are guided by the particle collision surface (224) onto a first sheet member (91). This suppresses direct collision of particles emitted from the supply cylinder (21) with a second sheet member (92) on the second sheet conveying roller (41). Scattering of particles that have collided with the second sheet member (92) around the first sheet member (91) and the second sheet member (92) is thus suppressed.
