摘要： An absorbent article that enables the presence of moisture, for example, derived from urination to be correctly recognized. The absorbent article includes an outer sheet that is provided on a side facing 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 Y. Between the moisture visualizing elements and the liquid-absorbent structure, there is provided a cover sheet having a sufficient area to cover the moisture visualizing elements completely in the longitudinal direction as well as in the transverse direction and being bonded to at least one of the outer sheet and the absorbent structure. As the cover sheet, a hydrophobic fibrous nonwoven fabric exhibiting a water pressure resistance in a range of 40 to 500 mm is used.
