Abstract
A polymer provided region (13) at which a superabsorbent polymer (12) is provided, and a polymer non-provided region (14) at which the superabsorbent polymer (12) is not provided are formed, a liquid diffusion sheet (15), that promotes diffusion of body fluid in a plane direction, is staked to be adjacent to a skin side surface of a lower layer sheet (11), and an upper layer sheet (10) is bonded with the liquid diffusion sheet (15) under a state that the upper layer sheet (10) contacts the liquid diffusion sheet (15), at the polymer non-provided region (14) to form a polymer sheet (4).
Claims5
An absorbent article, comprising
- a polymer sheet in which a superabsorbent polymer is provided between an upper layer sheet provided at a skin side, and a lower layer sheet provided at a non-skin side,
- wherein a polymer provided region at which the superabsorbent polymer is provided, and a polymer non-provided region at which the superabsorbent polymer is not provided are formed in the polymer sheet,
- wherein a liquid diffusion sheet that promotes diffusion of body fluid in a plane direction is stacked to be adjacent to a skin side surface of the lower layer sheet, the liquid diffusion sheet having a liquid permeability in a thickness direction of the liquid diffusion sheet that is lower than a liquid permeability of each of the upper layer sheet and the lower layer sheet, and
- wherein the upper layer sheet is bonded with the liquid diffusion sheet under a state that the upper layer sheet contacts the liquid diffusion sheet, at the polymer non-provided region.
