Absorbent article

1. An absorbent article including an elongated body, the body including a liquid-permeable top sheet, a liquid-impermeable bottom sheet, and an absorber provided between the top sheet and the bottom sheet, wherein:

compressed grooves are formed in the body from the top sheet toward the bottom sheet,

the compressed grooves include a pair of central compressed grooves formed substantially along a longitudinal direction of the body in line symmetry with respect to a centerline extending in the longitudinal direction of the body serving as an axis of symmetry, a pair of front lateral side compressed grooves formed in line symmetry with respect to the centerline serving as an axis of symmetry on a front lateral side of the central compressed grooves, and a pair of rear lateral side compressed grooves formed in line symmetry with respect to the centerline serving as an axis of symmetry on a rear lateral side of the central compressed grooves,

each of the pair of the front lateral side compressed grooves and the pair of the rear lateral side compressed grooves includes a first compressed groove and a second compressed groove positioned more distant from the centerline than the first compressed groove,

the first compressed groove and the second compressed groove have a circular arc shape, and are disposed such that inner circular arcs of both compressed grooves face each other, and

an extension line of the central compressed grooves passes between an end of the first compressed groove and an end of the second compressed groove, and does not pass between another end of the first compressed groove and another end of the second compressed groove.

2. The absorbent article as claimed in claim 1 , wherein a line segment connecting both ends of the first compressed groove and a line segment connecting both ends of the second compressed groove form an angle of 30° to 60° with the centerline.

3. The absorbent article as claimed in claim 1 , wherein

in a direction in which a line segment connecting both ends of the first compressed groove extends,

the end of the second compressed groove closer to the central compressed grooves is offset to one side in the direction relative to the end of the first compressed groove closer to the central compressed grooves, and

the end of the second compressed groove more distant from the central compressed grooves is offset to the one side in the direction relative to the end of the first compressed groove more distant from the central compressed grooves.

4. The absorbent article as claimed in claim 3 , wherein

in the direction in which the line segment connecting both ends of the first compressed groove extends,

a distance between a midpoint of the line segment connecting both ends of the first compressed groove and the end of the second compressed groove closer to the central compressed grooves is 0 to 0.15 times a length of the line segment connecting both ends of the first compressed groove.

5. The absorbent article as claimed in claim 3 , wherein a distance between the line segment connecting both ends of the first compressed groove and the line segment connecting both ends of the second compressed groove is 0 to 0.2 times a length of the line segment connecting both ends of the first compressed groove.

6. The absorbent article as claimed in claim 1 , wherein the first compressed groove and the second compressed groove has a shape of a circular arc having an angle of 135° to 180°.
