Between piece 11 be not in contact with the skin face of wearer, to also can be improved skin sense of touch (sense of touch).
Even if assuming that absorber 10 absorbs excretion moisture and expands and press section 40 is made to deform and block, can also pass through
The bump 110 of intermediate 11 inhibits the decline of gas permeability.In such manner, it is possible to inhibit under the gas permeability after urination (excretion)
Drop.
It is accordingly possible to ensure the comfort of the wearer of wearing paper nappy 1.
(2) in the case where containing super absorbent resin in absorber 10 as in this embodiment, although water imbibition
The expansion of absorber 10 is easy to cause when being improved, but absorbing water, thus, press section 40 is easily deformed and blocks.As a result,
It is easy to cause gas permeability to decline.On the other hand, due to being provided with bump 110 on the intermediate 11 of present embodiment, because
This, is able to suppress the decline of gas permeability.
(3) due to including non-overlap area not Chong Die with press section 40 when looking down in the configuring area of bump 110
Therefore domain can prevent whole bumps 110 from becoming together with the press section 40 for deforming and blocking when absorber 10 absorbs water
Shape, to facilitate the decline of inhibition gas permeability.
(4) in addition, due to containing overlay region Chong Die with press section 40 when looking down in the configuring area of bump 110
Domain, therefore, the access of the air to circulate in press section 40 and bump 110 respectively is connected or branch opens, and helps to mention
Highly-breathable.
In the present embodiment, when looking down, press section 40 is Chong Die at multiple positions with bump 110, therefore, even if
The bump 110 of a part and the press section 40 of a part deform and block together, but as long as the press section 40 of other parts does not have
There is deformation and block, it will be able to which gas permeability is reliably suppressed by the bump 110 of other parts that are undeformed and not blocking
Decline.
