    • A disposable diaper, which has fastening sheets on two side portions of a back side and which can be used with an ordinary fastening method but also a cross fastening method. The diaper has fastening sheets individually formed on the two side portions of the back side of the diaper and each including: joint ears formed to extend from outer side edges of each one of the sheets and to protrude sideward at two upper and lower stages; and facing fasteners disposed on inner sides of said joint ears, whereby the disposable paper diaper is worn on a body by fixing joint ears on a surface of an abdomen side of the diaper. Perforations leading from an outer side edge to an inner side are formed in a portion of the fastening base sheet between the joint ears. In perforations, a first perforation section extends from the outer side edge to an intermediate point P is a high tearing strength section S0 having a relatively coarse perforation interval, and a second perforation section from intermediate point P to an inner end is a low tearing strength section S1 having a relatively fine perforation interval.
