Abstract
A disposable diaper includes a pair of tape fasteners 6 that are used to connect front and rear waist regions 8, 10 to each other and are attached to side flaps 14 in the rear waist region 10 of the diaper. Each of the tape fasteners 6 includes fibrous nonwoven fabric made of thermoplastic synthetic resin fiber and thermoplastic synthetic resin coated on a substantially whole area of an outer surface of the fibrous nonwoven fabric wherein the thermoplastic synthetic resin forms a substantially smooth synthetic resin layer on outer surfaces of the respective tape fasteners. Thus, a free portion of each tape fastener is reliably prevented from being disengaged from a target tape even when the outer surface of the tape fastener and an inner surface of an underwear rub together during use of the diaper.
