Claims

An absorbent article comprising an absorbent body, a surface sheet arranged on the side facing the skin from the absorbent body, and an intermediate sheet arranged between the absorbent body and the surface sheet,
In the surface sheet,
A plurality of first embossed rows in which a plurality of linear embossed portions are intermittently arranged in series so that the longitudinal direction of each linear embossed portion faces the same direction, and a plurality of linear embossed portions are connected to each linear embossed portion A plurality of second embossed rows intermittently arranged in series so that the longitudinal direction of the
The first embossed row and the second embossed row intersect each other,
A convex region defined by the first embossed row and the second embossed row and containing the constituent fibers in the entire thickness direction is formed,
A first high-density region having a higher density than the convex region is located at the intersection of the first embossed row and the second embossed row,
The plurality of linear embossed portions are formed only on the surface sheet,
A plurality of fused portions are formed in the intermediate sheet,
In plan view, the first high-density region and the fused portion at least partially overlap ,
A second high-density region having a higher density than a portion other than the fused portion is formed in the intermediate sheet,
the fused portion is defined by the second high-density region;
In plan view, the first high-density region and the second high-density region at least partially overlap,
The surface sheet has a flat non-skin facing surface,
In plan view, the surface sheet and the intermediate sheet are joined with an adhesive at a position where the first high-density region and the second high-density region at least partially overlap,
The first high-density region includes the ends of two linear embossed portions adjacent to each other across the intersection point in the first embossed row, and the two linear embossed portions adjacent to each other across the intersection point in the second embossed row. is a perfect circular area that touches the edge of
The absorbent article , wherein the overlapping area ratio of the first high-density region and the fused portion is 15% or more and 45% or less .

The first high-density region has a lower density than the second high-density region, and the second high -density region is arranged within a width of 0.05 mm or more and 0.30 mm or less surrounding the circumference of the fused portion. The absorbent article of claim 1, wherein the absorbent article is

The surface sheet and the intermediate sheet have pressed grooves that are integrally compacted,
3. The absorbent article according to claim 1 , wherein a plurality of regions in which said first high-density region and said second high-density region at least partially overlap exist near said compressed grooves.

The area of the convex region is larger than the area of the fused portion,
4. The absorbent article according to any one of claims 1 to 3 , wherein the convex region and the plurality of fused portions overlap in plan view.

It has a longitudinal direction corresponding to the front-rear direction of the wearer and a lateral direction orthogonal thereto,
Assuming that the maximum lateral length of the fused portion before liquid absorption is W1 and the maximum lateral length of the fused portion after liquid absorption is W2, the percentage of W2 to W1 (W2/W1 ) is 80% or more, the absorbent article according to any one of claims 1 to 4 .

It has a longitudinal direction corresponding to the front-rear direction of the wearer and a lateral direction orthogonal thereto,
