And since the elastic member 9 is arrange | positioned on the absorber 4 (so that it may overlap with the absorber 4) in the disposable diaper 1 of this embodiment, a gather is formed on an absorber and the absorber 4 is worn by the wearer. The absorbent body 4 can be tightly attached to the body to prevent the absorbent body 4 from separating from the wearer's body, and the pocket 11 is formed near the urination point of the absorbent body 4, so that the absorbent body 4 absorbs urine. Can provide space for urine to accumulate,
Leak prevention is also improved. Further, in the conventional pants-type disposable diaper as shown in FIG. 7, excrement exceeding the leg gathers leads to leakage. However, in the disposable diaper 1 of the present embodiment, the gathers are formed on the absorber 4. Since the absorber 4 is also provided outside the gather, the leakage prevention is further improved.
