Patented is a disposable diaper with a body-facing surface and a garment-facing surface. An adhesive tape is provided on the garment-facing surface for holding the diaper in a rolled-up state for disposal. The adhesive tape comprises a first tape and a second tape attached to the garment-facing surface, which are aligned along a straight line. The first tape is folded back in two sections so that opposite ends of the first tape point in one direction of the straight line. The two sections define a first inner tape section lying on a side of the garment-facing surface and a first outer tape section overlaid on the first inner tape section from outside. A surface of the first inner tape section opposed to the garment facing surface is fixed in a vicinity of the end of the first inner tape section directly to the garment-facing surface. It is spaced, in a vicinity of a fold contiguous to the first outer tape section, from the garment-facing surface. The first outer tape section is coated, at least partially on a surface opposed to the first inner tape section, with an adhesive so it is temporarily fixed to at least one of the first inner tape sections and the garment-facing surface in such a manner as to be released. The second tape is folded back in two sections and overlaid so that opposite ends of the second tape point in an opposite direction of the straight line. The two sections define a second inner tape section lying on the side of the garment-facing surface and a second outer tape section overlaid on the second inner tape section from outside. The second tape section is at least partially interposed, in the vicinity of the fold of the first tape, between the first tape and the garment-facing surface. The second inner tape section is fixed directly to the opposing garment-facing surface. The second outer tape section is fixed to the opposing first inner tape section.
