Abstract
An open-type disposable wearing article composed of a front waist region, a rear waist region and a crotch region. These regions are all elastically stretchable. The article includes first and second stretchable zones respectively bifurcated at a transverse middle of the crotch region so as to extend to lateral zones of the front and rear waist regions, respectively, and third stretchable zones defined by zones other than the first and second stretchable zones. The first and second stretchable zones exhibit a stretch stress higher than a stretch stress of the third stretchable zones. Loop members are provided to the second stretchable zone in the lateral zones of the rear waist region and hook members are provided to the first stretchable zone in the lateral zones of the front waist region.
