Patent ID: 8183431

Claim:
An absorbent body comprising: a first absorbent body; and a second absorbent body includes an absorbent polymer, wherein each of the first and the second absorbent body includes: a plurality of low fiber basis weight regions; and a plurality of high fiber basis weight regions, wherein the low fiber basis weight regions, which are formed continuously along a first direction have a fiber basis weight that is less than an average fiber basis weight of the absorbent body, the high fiber basis weight regions, which are formed on both sides of the low fiber basis weight regions in a second direction perpendicular to the first direction along the low fiber basis weight regions, have a fiber basis weight that is greater than the average fiber basis weight of the absorbent body, a content of fibers oriented toward the first direction, in the fibers which make up each of the high fiber basis weight regions is greater than a content of fibers oriented toward the second direction in each said high fiber basis weight region, and a content of fibers oriented toward the second direction, in the fibers which make up each of the low fiber basis weight regions is greater than a content of fibers oriented toward the first direction in each said low fiber basis weight region, the first absorbent body and the second absorbent body are layered in a thickness direction of the absorbent body, the low fiber basis weight regions of the first absorbent body and the second absorbent body face each other in the thickness direction, and the high fiber basis weight regions of the first absorbent body and the second absorbent body face each other in the thickness direction.
