A disposable diaper comprising an absorbent core disposed between a liquid-impermeable backing sheet and a liquid-permeable facing sheet and having means for closing and fastening the diaper around the waist which are independent from means for sealing the diaper around the thighs of the wearer. The diaper employs two regions of adhesive for this purpose. The first said region is preferably located at the upper end of the diaper and comprises two adhesive areas at or near the corners of the diaper. The second adhesive region is located at the other end of the diaper and comprises two adhesive areas which are located in the side margins of the diaper and are spaced away from the corners at said other end. There are slits between the corners of the diaper and the adhesive areas of the second adhesive region. These slits extend inwardly from the side margins of the diaper toward its center.
