A topic is to provide a disposable wearing article which is utilized to move an absorption body upward when an upper part of a waist region is moved upward. A solution for the topic is to provide the disposable wearing article such as a diaper (10) with a vertical direction, a transverse direction (X) and a front-rear direction intersected with the aforesaid vertical direction and the transverse direction (X) The diaper (10) comprises a skin-facing surface and a non-skin-facing surface opposite to the skin-facing surface, a front waist region (13), a rear waist region (14), and a crotch region (15) arranged between the front waist region (13) and the rear waist region (14) and provided with an absorption body (85) for absorbing body fluid. The rear waist region (14) includes a band-like region (23) located on the skin-facing surface and extending in the transverse direction (X) and a downwardly-openable pocket (30) located on the non-skin-facing surface and facing the band-like region (23) in the front-rear direction at the center in the transverse direction (X). The pocket (30) has a pocket outer region (43) extending upward from the crotch region (15) side and a pocket inner region (42) which faces both the pocket outer region (43) and the band-like region (23) in a front-rear direction, is continuous with the pocket outer region (43) through a bend section (33) extending in the transverse direction (X), and extends downward from the bend section (33) to connect with the band-like region (23). The rear waist region (14) has first affixation regions (81A) which are utilized for fixing the band-like region (23) and the pocket inner region (42). The first affixation region (81A) in the transverse direction (X) has an inner portion (81b) which is located more inward than one of a side edge (85c) of an absorption body (85) or an imaginary line (L3) extending upward through the side edge (85c) of the absorption body (85) and an outer portion (81c) which is located more
