The present invention aims to provide a disposable wearing article improved so that tape fasteners attached to the article can be reliably protected against falling off from the article.A disposable wearing article (1) has its outer surface formed from a nonwoven fabric of thermoplastic synthetic fibers. The front and rear waist regions (5, 6) of the article are bonded together at a plurality of heat-sealed spots(15) arranged along respective lateral edge portions (9a,9b) of the front and rear waist regions (5,6) defining a waist hole(11) and a pair of leg holes(12). Each lateral edge portion (9a, 9b) is provided on the outer surface thereof with a tape fastener (16) folded in a Z-shape with extendability. The tape fastener (16) is adhesively bonded to at least one of the heat-seal spots (15) at a single bonding location on one of the lateral edge portions (9a,9b) of one of the waist regions (5,6) and the tape fastener (16) comprises first, second and third tape sections (51, 52, 53) connected together.
