The present invention provides a disposable wearing article adapted to restrict development of longitudinal creases in a crotch region of the wearing article which often occur when it is put on a wearer s body by forming a high stiffness region in a bodily fluid absorbent structure thereof. A bodily fluid absorbent structure 24 includes an absorbent core 26 an upper sheet 27 covering an upper surface of an absorbent core 26 and a lower sheet 28 covering a lower surface of the absorbent core 26. Of the bodily fluid absorbent structure 24 at least an area extending in a central portion of a crotch region 13 is formed with a high stiffness region 61 including a plurality of debosses 31. The debosses 31 are respectively shaped so that a length dimension W2 thereof in a transverse direction X is longer than a length dimension W1 thereof in a longitudinal direction Y. The high stiffness region 61 includes a plurality of longitudinal low stiffness zones 64 extending in the longitudinal direction Y and formed with none of the debosses 31 a plurality of transverse high stiffness zones 62 formed with the debosses 31 arranged intermittently in the transverse direction X and transverse low stiffness zones 63 each lying between each pair of the transverse high stiffness zones 62 being adjacent in the longitudinal direction Y and formed with none of the debosses 31.
