Une couche jetable (10) comprend : une ceinture (80) disposée dans une région de tronc arrière ; et une partie de corps (11) comprenant un noyau absorbant (31), qui est constituée d'un élément disposé sur le côté de la surface non tourné vers la peau par rapport à la ceinture. Sur le côté non tourné vers la peau de la ceinture, un espace de réception (AS) ouvert vers le côté d'une région d'entrejambe est formé. La partie de corps a une partie d'évidement (115) où le bord d'extrémité avant (11F) de la partie de corps est en retrait vers le côté arrière. La partie d'évidement (115) est située de manière à chevaucher le centre de la largeur du corps. La ceinture est disposée de manière à chevaucher le centre de la largeur du corps. Dans un état naturel à double plis où la couche jetable est pliée au niveau de la région d'entrejambe de telle sorte que la ceinture est maintenue par la partie de corps, avec une première ligne pliée s'étendant dans la direction de la largeur W définie comme un point de base, la ceinture a une partie d'exposition (88) chevauchant la partie d'évidement dans la direction de l'épaisseur.
