Abstract
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 includes a topsheet, a backsheet and a liquid-absorbent structure interposed between these top- and backsheets. The backsheet includes first and second backsheets and the first backsheet is formed on its side facing the liquid-absorbent structure with an indicator adapted to develop a color reaction when the indicator comes in contact with at least one of moisture and body exudates. A plurality of such indicators is arranged to extend in a longitudinal direction and to be spaced apart from each other in a transverse direction. The liquid-absorbent structure includes a liquid-absorbent core and a wrapping sheet adapted to wrap the core. A bottom sheet as a hydrophobic bottom element is interposed between a bottom surface of the core and a bottom region of the wrapping sheet as a hydrophobic bottom element.
