Claim:
An open-type disposable diaper comprising: in a longitudinal direction, a front waist region, a rear waist region and a crotch region extending between these waist regions and contoured by transversely opposite side edge portions extending in said longitudinal direction and front and rear end portions extending in a transverse direction of said diaper orthogonal to said longitudinal direction, said side edge portions comprising opposite front side edge portions having a longitudinal length that extends from the crotch region to the front end portion and opposite rear side edge portions having a longitudinal length that extends from the crotch region to the rear end portion, said diaper further includes two pairs of releasable connecting means that extend transversely outward from the transversely opposite side edge portions in parallel to each other in said transverse direction and serving to connect said side edge portions of said front and rear waist regions together, said front and rear side edge portions being unconnected directly to one another along their entire longitudinal lengths and being indirectly connected to one another by said releasable connecting means which extend transversely outward from the transversely opposite side edge portions so as to define an open-type diaper, said two pairs of connecting means being elastically stretchable in said transverse direction, each of said two pairs of connecting means including a connecting means that lies at a lower portion of said side edge portions and a connection means that lies at an upper portion of said side edge portions, the connecting means lying on the lower portions of said side edge portions having a stretch stress that is greater than a stretch stress of said connecting means lying at said upper portions of said side edge portions, said pairs of connecting means being connected to and extending outward from the rear waist region.
