The present invention provides a disposable wearing article improved so that leakage of body waste can be prevented, a change in color which might develop in an unused state of the wearing article can be inhibited and actually discharged body exudates can immediately cause an indicator to develop a change of color. A disposable diaper 1 includes a topsheet 11, a backsheet 12 and a liquid-absorbent structure 20 interposed between these top- and backsheets 11, 12. The backsheet 12 includes first and second backsheets 13, 14 and the first backsheet 13 is formed on its side facing the liquid-absorbent structure 20 with an indicator 15 adapted to develop a color reaction when the indicator 15 comes in contact with at least one of moisture and body exudates. A plurality of such indicators 15 is arranged to extend in a longitudinal direction Y and to be spaced apart from each other in a transverse direction X. The liquid-absorbent structure 20 includes a liquid-absorbent core 21 and a wrapping sheet 22 adapted to wrap the core 21. A bottom sheet 40 as a hydrophobic bottom element is interposed between a bottom surface 21b of the core 21 and a bottom region 24 of the wrapping sheet 22 as a hydrophobic bottom element.
