In the way of relative with the buttocks 81 of wearer, position is determined, by soft sheet element shape under wearing effect
This region entirety become is surrounded by each elastomer, therefore in form as bulging laterally.Herein, right
In common disposable shorts, due to the motion etc. in the wearing process of wearer, crotch region 13
Central part 13C be pulled to groin, or its local is sandwiched in gluteal fold and is likely to result in buttocks
A part is exposed to outside.Particularly, for front waist region 11, rear waist region 12 by the most independent
Sheet material formed, so-called three structure diapers, easily cause this situation, and have for preventing
The diaper of the hip of the buttocks that the covering of this situation exposes is known.But, this hip is to use
The sheet of the buttocks of outside is had been exposed to rather than for preventing the exposure of buttocks itself in cladding
Sheet.
With reference to (b) of Fig. 7, in the present embodiment, buttocks cover portion 78 is to be coated with the side of buttocks 81 entirety
Formula is such form in bulging laterally, even if therefore due to the motion of wearer, delimits buttocks cover portion
Buttocks correspondence elastomer the 76 and/or the 2nd rib collar elastomer 57b of 78 is by the central part to crotch region 13
13C layback is near, as represented by the imaginary line of (b) with Fig. 7, and the part quilt of bulging laterally
Extend the amount being equivalent to furthered, become the state fitting in buttocks 81, after being the most also not result in
The leg opening edge contracting width of side and make buttocks 81 expose.Thus, it is possible to prevent because buttocks 81 is from diaper 10
Expose and the sense of discomfort caused, excremental leakage.Particularly, in the diaper 10 of present embodiment,
The central part 13C of crotch region 13 is formed by the sheet of monolayer, is therefore sandwiched in and deforms between the crotch of wearer,
Thus, buttocks correspondence elastomer 76 is easily stretched downwards, it is possible to play this effect.
It addition, generally, in the region that absorber 51 exists, diaper is such form in bulging laterally
And being likely to result in visually can easily identifying as this in outward appearance is the situation of diaper, but in this enforcement

For than comprising rear waist elastic body 74 being positioned at inner side rear waist elastic by crotch region 13 side
The elongation stress of the preset width of the rear inner elastic region 73c of body 80 is low.Specifically, at each low back
In portion Hookean region 73a, 73b, 73c, for the preset width at the position outside the horizontal X of absorber 51
(the 171% when size under naturalness is set to 100% when the elongation of (30mm width) is 171%
Size) elongation stress for, rear inner elastic region 73c is about 3.0N～8.0N, hip resilient
Portion 77 is about 0.5N～5.0N, the 2nd rib collar elastomer 57b of leak-proof cuff the Hookean region formed pre-
The elongation of fixed width degree is that elongation stress when 171% is about 1.0N～5.0N, and the relevant pass of elongation stress
System is, rear inner elastic region 73c > Hookean region >=hip resilient of being formed by the 2nd rib collar elastomer 57b
Portion 77.
In order to make buttocks cover portion 78 fluffy bulging laterally to stretch tight with wrapping into buttocks and the strongest degree
Tight buttocks, preferably is set as comparing by the elongation stress delimiting each Hookean region in buttocks cover portion 78
Low, but it is preferred that there is required elongation in the region of the stably waistline of holding (hold) wearer
Stress.In the present invention, the elongation stress of each Hookean region is described dependency relation, wears for holding
The region of the waistline of the person of wearing, particularly abut against with needing most the position residing for the ilium being held stably
Rear inner elastic region 73c there is required elongation stress and can be effectively prevented under wearing effect
Diaper skew is glided, and by the elongation stress of other Hookean region is set to than this rear inner elastic
The elongation stress of region 73c is low, is not result in giving by tightening the sense of discomfort etc. caused.
