(3) action effect
The thickness of absorber 13 is changed using the second width broken line FW2 as boundary.Thus, with the second width broken line
It when FW2 is basic point folding absorbent article, can be folded by basic point of the boundary of thickness change, and make folding position stable.In addition,
In folding absorbent article, the relatively thin side of thickness is connect by the thickness direction folding along the relatively thick side of thickness
The relatively thin side of thickness to be folded in the way of covering on the relatively thick side of thickness.Absorbent commodity after folding
Thickness easily become uniform, and can minimize.Thus, user can easily carry the absorbability thing being miniaturized
Product.
Due on rear waist region S2 absorber 13 because towards skin with respect to the chevron broken line that surface side T1 is protruded shape
It is accustomed to (Japanese into the folding having towards the convex of wearer side：Roll over り addictions), therefore, rear waist region S2 male member laminating
The body of wearer.Thus, it is possible to be leaked after suppressing.For example, as the absorbent commodity of disposable diaper generally in rear waistline area
Domain S2 is formed with the bag portion for storing excrement.Thus, when rear waist region S2 fits in the body of wearer, for storing
The space of excrement disappears, and causes to leak if body is fitted in.In contrast, being used as the absorbability of pants type sanitary napkin
Article is sought to prevent menses are transmitted to rear side from leaking always.Menses autonomous agent top flat 11 on sanitary napkin is moved to absorber 13.
By making the body of rear waist region S2 laminating wearers, the lateral absorber 13 of the easy autonomous agent top flat 11 of body fluid is moved, and energy
Leaked after enough suppression.

It is swollen, and the body that it can be made to fit in wearer.Wearing feeling during wearing absorbent commodity 1 can be improved, in addition, by carrying
High stickiness is leaked after can preventing.
Generally, in order to cover buttocks, rear waist region S2 area is more than front waist region S1 area.Therefore, outside
Rear waist region S2 is configured as laterally extending compared to front waist region S1 in the state of side engagement portion 29 has been engaged.Example
Such as, by basic point of front and rear broken line FL1, FL2 by outer side engagement portion forward waist area S1 sides fold when, if fold area
It is less, then possibly rear waist region S2 can not be rightly folded compared to the part that front waist region S1 extends laterally.But,
, also can be proper in the case that the area of folding is less by the way that outer side engagement portion 29 is folded to rear waist region S2 sides
Locality is folded.Thus, it is possible to be folded in stable position, and it can minimize.
Due in front waist region S1 the second width broken line FW2 and rear waist region S2 the second width broken line FW2
At least any broken line is not formed at in-leg compression unit, is hardened therefore, it is possible to suppress the second width broken line FW2.Further, since low back
The the second width broken line FW2 for enclosing region S2 is not formed at in-leg compression unit 81, therefore, the rear waistline with the body fit of wearer
Region S2 the second width broken line FW2 will not become really up to the mark, it is thus possible to suppress the deterioration of wearing feeling.
Overlapping with stretching region in absorber 13 is formed in part with the leading flank that through-thickness is compressed to planar
Shape compression unit 86 and rear side planar compression unit 87., can when using front and rear broken line FL1, FL2 as basic point folding absorbent article
Folded along the lateral border of absorber 13.But, may in the case where the sheet material for constituting front waist region S1 has retractility
Because the retractility of the sheet material causes the width of the part overlapping with stretching region of absorber 13 to become less than absorber 13 not
The width of the part overlapping with stretching region.When the width of the part overlapping with stretching region in absorber 13 is less than absorber
Using front and rear broken line FL1, FL2 as basic point folding absorbent article in the state of the width of 13 part not overlapping with stretching region
When, because the lateral border of absorber 13 does not extend along fore-and-aft direction L, therefore, folding position is unstable sometimes.But, due to
Because planar compression unit causes the rigidity rise of absorber 13, therefore, it is possible to suppress absorber 13 using the retractility of the sheet material
The width of the part overlapping with stretching region reduces.Thus, it is possible to by the width of the part overlapping with stretching region of absorber 13
