Abstract
The present invention provides an absorbent body containing absorbent fibers in which fiber orientation is mainly adjusted, and fiber basis weight and shape are additionally adjusted. The absorbent body 110 of the present invention is an absorbent body containing absorbent fibers, a plurality of low fiber basis weight regions formed continuously in the first direction with a fiber basis weight that is less than an average fiber basis weight of the absorbent body 110, and a plurality of high fiber basis weight regions, formed along and on both sides of the low fiber basis weight regions in relation to the second direction perpendicular to the first direction, with a fiber basis weight that is greater than the average fiber basis weight of the absorbent body 110. The content of longitudinally oriented fibers in the fibers 101 making up the high fiber basis weight regions is greater than that of laterally oriented fibers, and the content of longitudinally oriented fibers in the fibers 101 making up the low fiber basis weight regions is greater than that of laterally oriented fibers.
