Abstract

The present invention provides an absorbent structure to be used in an absorbent article such as a diaper, a training pant, an adult incontinence absorbent article, a bed mat, or the like, and the respective absorbent article. The absorbent structure of the present invention is able to rapidly acquire urine even against gravity as is quantified by the liquid drip off test defined herein.
