A disposable wearing article has its outer surface formed from a nonwoven fabric of thermoplastic synthetic fibers. A tape strip constituting each of the tape fasteners is folded in Z-or inverted Z-shape and attached in such folded state to the outer surface of the wearing article by means of first adhesive. As for a spot at which the tape strip is attached to the outer surface of the wearing article, the nonwoven fabric at least partially presents a film-like outer surface.

What is claimed is: 1. 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. 2. The wearing article according to claim 1, wherein said second bonding location is spaced inwardly in the transverse direction from said at least one of said heat sealed spots; said adhesive layer is disposed between, directly contacts and permanently bonds said second bonding location and said tape fastener; and second bonding location comprises a number of said synthetic fibers fused together. 3. The wearing article according to claim 2, wherein said second bonding location is inwardly spaced in the transverse direction from said at least one of said heat sealed spots by a section of said nonwoven fabric which is free of the fused synthetic fibers. 4. The wearing article according to claim 2, wherein said one of said front and rear waist regions further comprises an inner sheet different from said nonwoven fabric which is an outer sheet; and said inner sheet defines the inner surface of said one of said front and rear waist regions and is made of a thermoplastic synthetic material which is fused together with the synthetic fibers of said outer sheet in said second bonding location. 5. The wearing article according to claim 1, wherein said fused synthetic fibers define the outer surface of the single layer film. 6. The wearing article according to claim 1, wherein said tape fastener is bonded to said nonwoven fabric in a folded state in which the fastening element is located between and releasably attaches an upper fold and a lower fold of said tape fastener to hold said tape fastener in the folded state; said lower fold of said tape fastener comprising: opposite ends permanently bonded to said first bonding location and said second bonding location respectively, wherein said second bonding location comprises a number of said synthetic fibers fused together and is spaced inwardly from said first bonding location by a section of said nonwoven fabric which is free of the fused synthetic fibers, and a middle portion located between said opposite ends and bonded to said section of said nonwoven fabric by said adhesive layer. 7. The wearing article according to claim 1, wherein each of the respective lateral edge portions of said waist regions comprises multiple layers of non-woven fabric or plastic films all of which are fused together in said single layer film so as to be indistinguishable one layer from another in said single layer film. 8. The wearing article according to claim 1, wherein said fused synthetic fibers no longer retain their fibrous nature in said single layer film. 9. The wearing article according to claim 8, wherein the synthetic fibers retain their fibrous nature outside said single layer film where said synthetic fibers are bonded to said tape fastener by said adhesive layer. 10. The wearing article according to claim 1, wherein the at least one tape strip is a single tape strip folded in Z-or inverted Z-shape. 11. The wearing article according to claim 1, wherein the at least one tape strip is permanently bonded to a film-like spot formed on the outer surface of the waist regions, outside of the lateral edge portions.
