Since the followability of the front-rear extension part RL is improved, the followability of the cutout part 90 is also improved, and it becomes easier to continue covering the body with the front end part and the rear end part of the absorbent article.
  • the sheet pressing unit 88 may be arranged apart from the first edge 95 and the second edge 96. Since the sheet pressing portion 88 is not formed on the first end edge 95 and the second end edge 96 that form the cutout portion 90, the flexibility of the first end edge 95 and the second end edge 96 is ensured, and the cutting is performed. The apex 93 of the cutout portion 90 is easily deformed, and the former state is easily returned after the deformation. Therefore, when the posture of the wearer repeatedly changes, the absorbent article can follow the change in the posture of the body, and it is easy to continue covering the body in which the posture has changed.
  • the topsheet 11 and the non-skin surface sheet 20 are compressed in a region inside the side sheet 12 in the width direction, and the top sheet is located in a region outside the side sheet 12 in the width direction W. 11, the side sheet 12, and the non-skin surface sheet 20 are compressed.
  • the apex 93 of the cutout portion 90 is located on the article width center line 1WC, and is provided in a region where the surface sheet 11 and the non-skin surface sheet 20 are stacked (a region where no side sheet is arranged).
  • the first intersection 91 and the second intersection 92 of the cutout portion 90 are located outside in the width direction with respect to the article width center line 1WC.
  • the first intersecting point 91 and the second intersecting point 92 of the front cutout portion F90 are provided in a region where the surface sheet 11 and the non-skin surface sheet 20 are stacked (a region where no side sheet is arranged).
  • the first intersection 91 and the second intersection 92 of the rear cutout portion R90 are provided in a region where the topsheet 11, the sidesheet 12, and the non-skin surface sheet 20 are stacked.
  • the number of sheets at the first intersection point 91 and the second intersection point 92 is larger than the number of sheets at the apex 93, and the rigidity of the first intersection point 91 and the second intersection point tends to be high.
  • the body can be continuously covered by the front end portion and the rear end portion of the absorbent article.

Abstract

L'invention concerne un article absorbant qui suit facilement le mouvement du corps, même lorsque la posture d'un porteur change de manière répétée. Un article absorbant (10) a une direction avant-arrière, une direction de largeur qui est orthogonale à la direction avant-arrière, un noyau d'absorption et une partie de jonction de partie principale (61) qui doit être jointe à un article porté. Une partie en retrait (F90, R90), qui est dentelée vers l'intérieur dans la direction avant-arrière au centre de la direction de la largeur de l'article absorbant, est formée dans une partie d'extrémité avant et/ou une partie d'extrémité arrière de l'article absorbant. La partie en retrait a un pic (93), un premier point d'intersection (91) qui s'étend du pic à un côté de direction de largeur et se connecte à un bord d'extrémité de direction avant-arrière de l'article absorbant et un second point d'intersection (92) qui s'étend du pic à l'autre côté dans la direction de la largeur et se connecte au bord d'extrémité avant-arrière de l'article absorbant. Un premier bord d'extrémité (95) qui relie le pic et le premier point d'intersection et/ou un second bord d'extrémité (96) qui relie le pic et le second point d'intersection présentent une partie incurvée qui s'incurve.
