However, breathability and liquid-proofing properties are in a trade-off relationship, and if you try to achieve the required breathability, you will not be able to get liquid-proofing properties, and excreted fluid will leak from the vents. The conventional diapers mentioned above have these drawbacks, and it is a challenge to solve them.

供することにある。 Therefore, the purpose of the present invention is to prevent the leakage of excretory fluid from occurring outside the area to be sealed by the elastic bands around the legs placed on both sides, in other words, generally not directly related to the leakage of excretory fluid.
Furthermore, the present invention aims to provide a disposable diaper that can solve the above-mentioned problems at once by providing a ventilation porous region on the outside of the side flaps having a ventilation function.

該スリーブの中央に長さＬにわたつて位置する。 As shown in FIGS. 1 and 2, the diaper consists of a liquid-permeable top sheet 1, a liquid-impermeable back sheet 2 that is wider than the top sheet and partially extends outward from its side edges, and these sheets. It includes a liquid absorbent core 3 interposed between a top sheet and a back sheet, side flaps 4 extending outward from both side edges of this core, and a barrier 5 located extending in the longitudinal direction of this side flap. This barrier 5 is
Sleeve 7a formed from a part of liquid-proof sheet 6
and an extension part 7b extending outward from this. Inside this sleeve 7a, there is located an elastic band 8 that extends in the vertical direction and has elasticity. In such a barrier 5, the lower part of the sleeve 7a and the lower surface of the extension part 7b are joined to the upper surface of the side flap 4, and both longitudinal ends 9 of the sleeve 7a are folded back and joined to the outside. The sleeve 7a is raised by the contraction of the elastic band 8. However, both ends of the sleeve 7a may be folded inward and joined together, and even in this case, the sleeve 7a will still rise due to the contraction action of the elastic band 8. The elastic band 8 is located inside the sleeve 7a and over a length L in the center of the sleeve.

The back sheet 2 having such ventilation holes 12 only in the region 11 can be provided by, for example, embossing the region 11 and biaxially stretching the entire back sheet 2, and then tearing off the embossed portion. In this way, it is preferable to provide the ventilation holes 12 in the entire area 11 from the viewpoint of processing, but at least the back sheet 2 (diaper)
The intended purpose is achieved by providing ventilation holes 12 in the corners of the belt and the vicinity 13 thereof, specifically, in the range from the longitudinal end of the back sheet 2 to the vicinity of the longitudinal end of the elastic band 8. can do.

こともできる。[Effects of the invention] According to the diaper of the invention, when the diaper is worn, the ventilation porous regions 11 of the side flaps 4 near the corners of the waist circumference of the diaper allow ventilation to the inside and outside of the diaper. This allows you to minimize stuffiness inside the diaper. At the same time, it is an exaggeration to say that there is no leakage of excreted liquid from the vented porous area, as this is the area of the diaper where excreted liquid flows from the crotch area of the diaper and is least likely to reach the area near this corner. Moreover, in order to improve air permeability, the ventilation holes can be formed relatively large.
