In the disposable diaper of the present embodiment, the direction of the pressure vector at the time of fitting becomes oblique because the back-side elastic portion 9 and the three-dimensional guard 6 act in conjunction with each other, so that the mutually weak stresses are also reduced. The 9 and the three-dimensional guard 6 fit well on the wearer and are less likely to slip off, so that lateral leakage from the crotch to the back is prevented. Further, a pocket portion is formed between the plurality of three-dimensional guard elastic members, and even if excrement exceeds the three-dimensional guard, the excrement is collected by these pocket portions, and leakage from the leg portion can be effectively prevented.

However, the present invention is not limited to this, and an elastic member may be provided on the leg portion. It is good also as a form which has a leg gather. In this case, the function of the leg gathers further improves the leakage prevention effect. Further, in the description of the above-described embodiment, the deployment type disposable diaper has been described as an example.
The present invention is also applicable to pants-type disposable diapers (in this case, the longitudinal direction is the vertical direction of the disposable diapers), sanitary napkins, and the like. In addition, although the base end 60 of the three-dimensional guard is illustrated as being located at the leg portion 7, that is, not located on the absorber, the base end 60 is not limited thereto.
It may be located on the absorber 4. In this case, even if the excrement gets over the three-dimensional guard, the excrement is absorbed by the absorbing portion outside the base end, so that the leakage prevention effect is further improved. Further, a solid guard provided with a solid guard elastic member may be formed on both sides or one of the back sides to prevent leakage from the waist. Further, the three-dimensional guard or the elastic member disposed on the three-dimensional guard may be curved, and the end of the three-dimensional guard or the elastic member disposed on the three-dimensional guard may be adjacent to the support portion of the tape fastener. Further, the free end from the base end of the three-dimensional guard may be laminated with a liquid-permeable or liquid-impermeable film. Further, the three-dimensional guard itself may be formed of a stretchable sheet material.

Further, a water-repellent backing paper, a nonwoven fabric and a liquid-impermeable film may be used as the material constituting the absorber, and the lower portion and the side portion of the absorbing portion may be covered with these materials. In this case, it is effective to prevent excreta once absorbed by the body pressure of the wearer from seeping out from the absorber. Further, the leak-proof sheet extends to the base end of the three-dimensional guard or the side edge of the absorber, and the leak-proof sheet does not extend to the leg, and the leg is disposed on the sheet material 61 and the surface of the leak-proof sheet. It is good also as a form formed from the outer layer nonwoven fabric formed. In this case, the leg portion has more air permeability, and the stuffiness prevention effect is further improved.
In this case, the sheet material 61 preferably has a strength in the CD direction of 1000 cN / 50 mm or more.
More preferably, it is not less than 00 cN / 50 mm. Here, the strength is measured as follows. 25 mm in width in the machine direction (MD), and a direction perpendicular to the machine direction (C
A test piece having a length of 150 mm was cut out in D). This test piece was subjected to a tensile test using a Tensilon tensile tester (manufactured by Orientec Co., Ltd.) at a chuck distance of 50 mm and a tensile speed in the CD direction of 300 mm / min to measure the strength at break.
