Abstract:
An underpants-type disposable diaper has a display sheet containing a resin film between an inner member and at least one of a front side outer member and a back side outer member. A cover nonwoven fabric is provided with a plurality of holes having intervals and penetrating a front and a back is interposed from at least a crotch side edge of an outer member overlapping the display sheet to a side of a waist opening between the display sheet and a liquid impervious sheet. An internal surface and an external surface of the cover nonwoven fabric are bonded to facing surfaces, respectively, through a hot melt adhesive. Compatibility between prevention of deterioration of appearance of the display sheet and prevention of a decrease in air permeability is achieved.
