The present invention aims to provide an absorbent article enabling the presence of moisture, for example, derived from urination to be correctly recognized. An outer sheet 9 is provided on its side facing wearer's skin, i.e., on its side facing a liquid-absorbent structure 10 with moisture visualizing elements 21. The moisture visualizing elements 21 are formed by coating the outer sheet 9 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 21 extend in a longitudinal direction Y. Between the moisture visualizing elements 21 and the liquid-absorbent structure 10, there is provided a cover sheet 22 having a sufficient area to cover the moisture visualizing elements 21 completely in the longitudinal direction as well as in the transverse direction and being bonded to at least one of the outer sheet 9 and the absorbent structure 10. As the cover sheet 22, a hydrophobic fibrous nonwoven fabric exhibiting a water pressure resistance in a range of 40 to 500 mm is used.
