Specifically, when unfolding the side flap, a finger is inserted between the fastening member 20 and the side seat 4 so as to face the fold FL side of the side flap from the inner side in the width direction of the side extension portion 12. And gradually peel off the second joint. At this time, since the rear waist area S2 side of the side flap is the peeling start location, it is easier to deploy.

Abstract

　Un article absorbant (1) comprend une feuille de corps principal qui recouvre un corps absorbant, et des éléments de fixation (20) qui sont reliés aux bords extérieurs de la feuille de corps principal dans le sens de la largeur. Les bords extérieurs de la feuille de corps principal dans le sens de la largeur sont repliés le long de lignes de pliage orientées dans le sens de la longueur du corps absorbant, et sont temporairement fixés de manière séparable à la feuille de corps principal en des points plus près de l'intérieur dans le sens de la largeur que les lignes de pliage, au moyen d'une deuxième partie de liaison (32). Les deuxièmes parties de liaison sont positionnées à la fois plus à l'extérieur dans le sens de la longueur que les zones de largeur s'étendant dans le sens de la largeur depuis les éléments de base de fixation où la feuille de corps principal et les éléments de fixation se chevauchent, et plus à l'intérieur dans le sens de la longueur que les zones de largeur.
