[0013] In the disposable diaper according to the present invention, the number of elastic elastic members arranged from the crotch part to the back body part is two to two.
The number is preferably eight, and more preferably three to six. If the number of elastic elastic bodies exceeds eight, the wearer's skin may be tightened more than necessary, and a single elastic body has little effect, and neither is preferable. . In addition, the interval between the elastic members increases as approaching the side edge portion of the rear body portion, thereby providing a wide range of fit around the waist. Also, at least one of the plurality of elastic bodies disposed on the back body side edge is disposed on the waist side from the middle point of the entire length of the back body side edge, and at least one is around the leg from the middle point. Preferably, it is arranged on the side. It is not preferable that the stretchable elastic member is arranged on one side of the rear body side edge, because the fit around the waist becomes poor.

Further, it is desirable that the interval between adjacent elastic members is equal. If the diaper is arranged unevenly, stress is concentrated only in that portion, and the diaper is strongly pressed against the wearer's skin, which is not preferable since the diaper is likely to have marks. Further, it is preferable that the plurality of elastic elastic members disposed on both sides of the absorber in the crotch part are disposed apart from the side edge of the absorber. When the elastic elastic body is in contact with the side edge of the absorber, the followability of the diaper to the wearer is inferior at the crotch, and a gap is formed between the body and the diaper at the leg opening, and urine and loose stool etc. It becomes easy to leak.

In the disposable diaper of the present invention, in the extended state, the width of the back body in the width direction is longer than the width of the front body and the crotch in the width direction. By adopting such a configuration, the length of the stretchable elastic body disposed on the back body can be increased, so that the portion of the stretchable elastic body that is in contact with the waist circumference increases and the fit of the waist circumference increases. It will be excellent. The ratio of the width of the front body to the width of the back body is preferably from 1: 1.3 to 1: 3, preferably from 1: 1.4 to 1: 2.5. More preferably, there is. If the length of the back body portion in the width direction is out of this range and becomes shorter, it is difficult to obtain the above-described effects. Conversely, if it becomes longer than this range, the length of the back body portion becomes too long and the diaper And the fit around the waist deteriorates.
