Abstract A disposable diaper comprising, an absorbent pad assembly having an absorbent pad, opposed first and second surfaces, and at least one side edge. The diaper has a pressure-sensitive tape strip having a first end section secured to the first surface of the pad assembly, and a second securement section extending past the side edge of the pad assembly. The fastener has a sheet having a first surface and a substantially adhesive-free second surface facing the second surface of the pad assembly and having a relatively high affinity for adhesive. The fastener also includes adhesive means intermediate the second surface of the sheet and the second surface of the pad assembly, with the adhesive means being located adjacent one end of the sheet and being spaced from the side edge of the pad assembly to retain the one end of the sheet to the second surface of the pad assembly.
