Abstract
The present invention provides a disposable diaper which prevents body waste from leaking sideways without sacrificing a bodily fluid absorbing capacity of a liquid-absorbent structure and to assure a high retention for urine and discharged feces. The waist elastic members includes first and second waist elastic members wherein elastic members extend in the transverse direction across opposite lateral regions so as not to present in central zones of front and rear waist regions. The second waist elastic members in the front waist region extend from transverse opposite side edges of the front waist region in the transverse direction beyond transverse opposite side edges of a liquid-absorbent core while the second elastic members in the rear waist region extend from transverse opposite side edges in the transverse direction and terminate short of the side edges of the core.
