## Abstract

An incontinence pad includes an absorbent body provided between a liquid permeable topsheet and a backsheet, a concave groove formed in a surface of the absorbent body on the liquid permeable topsheet side and extending along an approximately longitudinal direction of the groove, and a highly compressed portion formed in a bottom surface of the concave groove. The highly compressed portion includes a sloping element in a unit portion formed by dividing the concave groove in a longitudinal direction thereof and crossing the concave groove from one side edge to the other side edge, and is formed into a pattern obtained by repeatedly inverting the highly compressed portion of the unit portion in the longitudinal direction.

## Claims

### Claim 1

An absorbent article comprising:
a liquid permeable topsheet;
a backsheet;
an absorbent body provided between the liquid permeable topsheet and the backsheet;
a groove formed in a surface of the absorbent body on the liquid permeable topsheet side and extending along an approximately longitudinal direction of the groove; and
a highly compressed portion formed in a bottom surface of the groove, wherein
the highly compressed portion includes a slanted element in a unit formed by dividing the groove in a longitudinal direction of the groove, and is formed by substantially crossing the groove from one side edge to the other side edge so as to form a first pattern and is formed into a second pattern obtained by repeatedly inverting the first pattern of the highly compressed portion of the unit in the longitudinal direction.

### Claim 2 (depends on 1)

The absorbent article as claimed in claim 1, wherein the sloping element is composed of a straight line, a curved line or a combination thereof.

### Claim 3 (depends on 1)

The absorbent article as claimed in claim 1, wherein the highly compressed portion includes an arch element extending from both ends of the sloping element or neighborhoods thereof in approximately the longitudinal direction and formed into an curved shape protruding outward in the width direction.

### Claim 4 (depends on 1)

The absorbent article as claimed in claim 1, wherein the sloping element is composed of a single line or a double line.

### Claim 5 (depends on 1)

The absorbent article as claimed in claim 1, wherein the absorbent body has an absorbent body concave portion formed over a portion of the surface on the liquid permeable topsheet in a longitudinal direction of the absorbent article, the portion of the surface including a body fluid expelling area, and
an embossed part including the highly compressed portion is formed along the absorbent body concave portion.

### Claim 6 (depends on 5)

The absorbent article as claimed in claim 5, wherein the embossed part is narrower than the absorbent body concave portion.

### Claim 7 (depends on 5)

The absorbent article as claimed in claim 5, wherein the embossed part is wider than the absorbent body concave portion, and high-density areas obtained by compressing the absorbent body are formed on both sides of the absorbent body concave portion by providing the embossed part.
