Attachable-type disposable wearing article

An attachable-type disposable wearing article having:

• a crotch section containing a center of front-back direction, a ventral section extending forward of the center of the front-back direction, and a dorsal section extending backward of the center of the front-back direction,
• the attachable-type disposable wearing article comprising:
• attaching parts provided in opposed lateral portions of the dorsal section, and to be detachably attached to an exterior face of the ventral section,
• an absorber body disposed in a region including the crotch section,
• an end flap exclusive of the absorber body located backward of the absorber body in the dorsal section, and
• a deformable stretching/contracting member fixed to the end flap,
• the deformable stretching/contracting member having a pair of fixed areas fixed in lateral portions, respectively, opposed in a width direction of the end flap, and an unfixed area elastically stretchable/contractible in the width direction and located between the fixed areas,
• wherein the attachable-type disposable wearing article is configured so that, in a natural length state, as the unfixed area contracts, a pair of side areas of the end flap positioned lateral to the unfixed area are obliquely drawn closer to each other as they extend backward, which results in formation of obliquely backward portions at back edges of the side areas which are positioned more backward as they extend laterally, while a transverse portion extends in the width direction at a back edge of an intermediate area located between the pair of side areas are formed, and
• in a spread state, a back edge of the end flap extends along the width direction over an extent including from one of the obliquely backward portions to the other.
