Claim:
A disposable wearing article, comprising: a crotch region; a front waist region extending forward in a longitudinal direction of said article from said crotch region; a rear waist region extending rearward in the longitudinal direction from said crotch region; an outer surface of said front and rear waist regions is defined by a nonwoven fabric made of thermoplastic synthetic fibers; each of said regions having a pair of transversely opposite lateral edge portions extending in the longitudinal direction; each of said front and rear waist regions further including an end portion extending in a transverse direction of said article between the lateral edge portions thereof; said front and rear waist regions are bonded together at a plurality of heat-sealed spots arranged along the respective lateral edge portions of said waist regions to define a waist hole and two leg holes, whereby said disposable wearing article is a pants-type article; in each of said heat-sealed spots, a number of said thermoplastic synthetic fibers are fused together forming fused synthetic fibers; and tape fasteners, wherein each tape fastener is adhesively bonded to a first bonding location on the transversely opposite lateral edge portions at said heat-sealed spots and a second bonding location on the outer surface of a waist region, each tape fastener comprising: at least one tape strip with extendibility; and an adhesive fastening element provided on said tape fastener and releasably engageable with the outer surface of said article; wherein at least one of said heat sealed spots includes a single layer film in which the respective lateral edge portions of said waist regions are fused together and which is free of material of the fastening element of said tape fastener; wherein said at least one tape strip includes a first section permanently bonded on its inner surface to a bonding location, a third section continuous with the first section and temporarily bonded on its inner surface to an outer surface of the first section, and a second section continuous with the third section and temporarily bonded on its inner surface to an outer surface of the third section, said at least one tape strip configured to curvedly extend outwards from the outer surface of the waist region; and wherein said single layer film extends through an entire thickness of each of the respective lateral edge portions of said waist regions and is present on the outer surfaces of both said waist regions, wherein an adhesive layer bonds the outer surface of the single layer film to the tape fastener; and wherein at least one of the tape fasteners attached to the bonded lateral edge portions is fastened in a waist-surrounding direction, and is configured to put the front and rear waist regions in close contact with a wearer's waist.
