It may put pressure on the product and impair the feeling of wearing it. However, in order to prevent leakage of body fluid, not only the entire area where the core is located is in close contact, but only the peripheral edge portion may be in close contact, and doing so reduces the risk of impairing the wearing feeling.

る。In FIG. 1, the diaper is composed of a laminate 1. The laminated body 1 is composed of a liquid-permeable top sheet 2, a liquid-impermeable back sheet 3, and a liquid-absorbent core 4 arranged between these sheets. The core 4 is formed in an hourglass or I shape, and has front and rear end edges 4A and 4B and both side edges 4C. The front and back sheets 2 and 3 are formed in such a size that their peripheral edges extend from the peripheral edge of the core 4, and their extended portions are joined to each other so that both side flaps 6 are formed.
A and 6B and both end flaps 6C and 6D are formed. Such a laminated body 1 is located substantially in the center of the laminated body 1 and has front and rear side regions 7B and 7B through a crotch region 7A which is formed narrowly.
It can be divided into C. The laminated body 1 is folded and folded in the crotch region 7A so that the topsheet 2 is located on the inner surface of the diaper, and is joined by the joining means 10 at both side edges of the front and rear side regions 7B and 7C. ,
A pair of leg openings 12 are defined. Torso opening 11
Elastic members 15 and 16 that expand and contract in the circumferential direction are attached to the front side region 7B including and the leg opening 12.

Includes the front edge 4A in its vicinity including the front edge 4A.
It is formed in a shape in which the thickness of the front end region is gradually reduced toward at least 10 mm. Such a shape is obtained by reducing or compressing the material in the relevant portion of the core 4 toward the front end edge 4A. The front and back sheets 2 and 3 extending from the front edge 4A are joined to each other to form a body opening edge 17. Although not shown, it should be understood that the rear region 7C is similarly configured.

付けられている。The front side region 7B is defined by a maximum of 20 mm above and below the front end edge 4A of the core 4, preferably 15 to 10 mm, and a waist region 7B 1 , a waist region 7B 1 and both leg openings. It has a waist region 7B 2 defined between the body 12 and a waist region 7B 3 defined between the waist region 7B 1 and the waist opening edge 17. Waist area 7B 1 , 7B 2 , 7B 3
A large number of elastic members 15 extend in the circumferential direction of the elastic members 15 and are arranged at intervals in the longitudinal direction thereof, and are fixed to the inner surface of the topsheet 2 or the front and backsheets 2 and 3 in an extended state. ing. Elastic member 15 in the waist region 7B 3
Each of a is the elastic member 1 in the waist regions 7B 1 and 7B 2 .
5b and 15c, the cross-sectional area and the elongation stress are set larger. Waist area 7B 1 , 7
Although the elastic members 15b and 15c in B 2 are made substantially equal to each other in terms of their cross-sectional area and extension stress, the arrangement spacing dimension of each elastic member 15b in the waist region 7B 1 is 7B 2 is set to be smaller than the arrangement interval dimension of each elastic member 15c,
Therefore, regarding the surface pressure per constant area, the waist area 7
B 1 is larger than the waist area 7B 2 . Elastic members 15b, 15 in the waist regions 7B 1 , 7B 2 , 7B 3
The c and 15a have a 50% elongation stress of 5 to 50 g per 150 mm in length, and are attached at an elongation rate of 1.1 to 2.5 times.

ればよい。With respect to the surface pressure per constant area, the waist region 7
In the above-described embodiment in which B 1 is larger than the waist region 7B 2 , the front end edge 4A of the core 4 located in the waist region 7B 1 and the vicinity thereof are less than the rigidity of the core 4 during wearing of the diaper. Therefore, there is an advantage that it does not separate from the wearer's skin, in other words, it adheres to the skin stronger than the waist area 7B 2 despite the rigidity of the core 4. However, on the other hand, increasing the surface pressure only in a part of the area may give the wearer a feeling of strangeness. Therefore, regarding the surface pressure per constant area, the waist circumference areas 7B 1 and 7B 2 are substantially equalized, but the waist circumference area 7B
It is preferable that B 1 is better than the waist region 7B 2 . To do this, as in the previous embodiment, the waist region 7B
The array spacing dimension of each elastic member 15b of 1
As well as smaller than that of the elastic member 15c of the B 2, each of the extension stress of the elastic member 15b of the waist regions 7B 1 may be decreased appropriately than that of each of the elastic member 15c of the waist region 7B 2. In order to reduce the size in this way, the material and the cross-sectional area of each of the elastic members 15b and 15c of the waist regions 7B 1 and 7B 2 are made substantially equal, and
Or each extension magnification of the elastic member 15b of the waist regions 7B 1 is made smaller than that of each of the elastic member 15c of the waist region 7B 2, waist region 7B 1, 7B 2 of the elastic member 15b, 1
The material of 5c and the expansion ratio may be made substantially equal, and the cross-sectional area of each elastic member 15b in the waist region 7B 1 may be made appropriately smaller than that of the elastic member 15c in the waist region 7B 2 .
【００１５】なお、弾性部材１５の断面形は、円形、角

ない。In the above description, the front side region 7B is concerned, but it goes without saying that the rear side region 7C may have the same structure as the front side region 7B or a slightly different structure.

ている。In the diaper thus constructed, the elastic members 15 are arranged closely above and below the front end edge 4A of the core with a narrow interval, and the core 4 is surely skin-skinned at the portion where the front end edge 4A and its vicinity are located. Since it adheres to the
There is no leakage from the front edge 4A. Waist area 7B 3
The elastic member 15a extends in the entire width direction of the front and rear side regions 7B and 7C so as to be substantially continuous in the waist circumference direction.

It is possible to improve the adhesion between the front end edge 4A of the core and its vicinity by using one or a plurality of relatively wide band-shaped elastic members, but in order not to impair the air permeability inside and outside the diaper. It is preferable to use a material having moisture permeability.

It is possible to surely bring the edge and the vicinity thereof into close contact with the wearer's body, and prevent body fluid from leaking from the edge without impairing the wearing feeling of the article. Also, when the thickness in the vicinity of the edge of the core gradually decreases toward the edge, the difference in level between the core and the body is smaller than in the case where it is not, and the appearance when worn is good. is there.
