Abstract
An absorbent article that enables the presence of moisture, for example, derived from urination to be easily recognized. The absorbent article includes an outer sheet provided on a side that faces a wearer's skin, i.e., on its side facing a liquid-absorbent structure with moisture visualizing elements. The moisture visualizing elements are formed by coating the outer sheet with hot melt composition comprising pH indicator mixed with pressure-sensitive adhesive ingredient. Two or more stripes of the hot melt composition forming the moisture visualizing elements extend in a longitudinal direction at least across a crotch region. Between the moisture visualizing elements and the liquid-absorbent structure, there is provided a barrier sheet or barrier sheets extending in a transverse direction so as to intersect the moisture visualizing elements comprising two or more stripes of the hot melt composition.
