As a result, the excreted liquid that has passed over the second flap portion 19 does not leak beyond the third flap portion 8 and is not absorbed, and urine flows toward both side edges of the absorbent article body 1 in the width direction. The excrement liquid does not leak from both side edges of the absorbent article body 1 in the width direction, and side leakage of excrement liquid such as urine can be reliably prevented. Furthermore, since the third flap portion 8 is formed of the hydrophobic sheet 6, it is possible to reliably prevent the excretory fluid from leaking.

Since the liquid-permeable sheet has a basis weight of g / m 2 and is formed of a woven or non-woven fabric using fibers having a fiber thickness of 2 denier to 10 denier, the diffusion sheet 15 allows the liquid-permeable top sheet 16 to The excreted liquid such as the absorbed urine is surely diffused and is evenly absorbed over substantially the entire surface of the absorber 4, so that the absorption efficiency is enhanced.

The dimension between 17 is 20 mm to 100 mm, and the second part on both sides is
Since the dimension of the flap portion in the width direction is 10 mm to 50 mm, the rising dimension of the second flap portion 19 is 10 mm to 50 mm.
Since it fits in the crotch part in the optimum condition, it can quickly diffuse and absorb excrement such as urine, and the absorption efficiency is improved so that the excrement does not leak. That is, it is generally said that the width of the crotch portion of a human is about 50 mm, and the dimension between the base end edges 17 of the second flap portions 19 on both sides may ideally be within the width dimension, but it is not always absorbed. The sex article main body 1 cannot always be applied to a fixed position. Therefore, the dimension between the base end edge portions 17 of the second flap portions 19 on both sides may require a width of 50 mm or more.
Numeral 19 dams solid matter such as stool, and when solid matter such as stool spreads, it becomes difficult for liquid such as urine to be absorbed, and even if the size between the proximal end portions 17 of the second flap portions 19 is too large, Therefore, the optimum size of the second flap portion 19 between the base end portions 17 is 20 mm to 100 mm.
