Abstract
A disposable wearing article is provided with a pair of tape fasteners each composed of inner and outer tape strips and a hook member. The outer tape strip has a proximal portion fixed to the side section of the rear waist region and a distal portion extending outwards from the side section. The inner tape strip has a proximal portion fixed to the side section, a first distal portion bonded to the distal portion of the outer tape strip, and a second distal portion extending outwards from the distal portion of the outer tape strip. The hook member is attached to at least the second distal portion of the inner tape strip. The tape fastener has first and second zones corresponding to the distal portions of the outer and inner tape strips. A stiffness of the second zone is lower than that of the first zone.
