At that time, menstrual blood bleeds into the pattern embossing component having a relatively large area, so that the user can visually recognize the pattern embossing component in which menstrual blood has oozed and judge the replacement time.

Abstract

La présente invention concerne un article absorbant capable d'améliorer la capacité d'absorption d'un fluide corporel tel que le sang menstruel ayant une viscosité élevée et produisant une sensation plus confortable pour un porteur lorsqu'il est porté. Un article absorbant (1) est pourvu d'une partie de corps principale (2), des parties d'aile (43) faisant saillie respectivement vers l'extérieur dans la direction de la largeur depuis la partie de corps principale, et des parties de rabat (60) faisant saillie respectivement vers l'extérieur dans la direction de la largeur depuis la partie de corps principale derrière les parties d'aile. La partie de rabat a un absorbeur de rabat (35), et une feuille de surface de rabat (12) située plus près du côté de surface de contact avec la peau que l'absorbeur de rabat. Dans la partie de rabat, une section gaufrée de rabat (70) obtenue par pression de l'absorbeur de rabat et de la feuille de surface de rabat dans une direction d'épaisseur est formée. La section gaufrée de rabat s'étend depuis l'intérieur de celle-ci dans la direction de la largeur vers l'extérieur de celle-ci dans la direction de la largeur vers le côté arrière de celle-ci.
