An elastic member was installed on the side flap portion extending to the side of the absorber as a means for preventing leakage of the excrement of the disposable diaper from the leg portion, and the side flap was attached to the leg portion by the expansion and contraction action of the elastic member. Things are generally well known.
Also, there is a disposable diaper having a pocket structure and a leak-proof wall at a side flap portion as described in Japanese Utility Model Application Laid-Open No. 58-18520 and Japanese Patent Application Laid-Open No. 59-53702.

形部位からの漏れが生じやすい。However, the disposable diaper provided with the above-mentioned means for preventing leakage from the legs cannot follow the movement of the legs of the wearer, and the clearance is formed in the legs, so that the excretion speed is high and the viscosity is high. It has poor leakage-preventing effect on diarrheal stool, loose stool, or a large amount of excreted urine and stool. In addition, since the absorber arranged between the top sheet and the back sheet is bonded and fixed to the two sheets, the absorber is easily deformed by the movement of the wearer and the absorption of excrement, and the absorption performance is significantly impaired, and the absorption performance from the deformed portion is significantly reduced. Leakage is likely to occur.
