La présente invention concerne un article absorbant (100), comprenant un corps principal absorbant (10) qui comprend en outre un corps absorbant (13) positionné entre une pluralité d'éléments de feuille (11, 12). Le corps principal absorbant (10) comprend en outre : une partie de surface supérieure (1) qui présente une surface qui entre en contact avec l'entrejambe de l'utilisateur ; et des parties de surface latérale gauche et droite (2, 3) qui s'étendent de la partie de surface supérieure (1) vers le côté de la partie de surface supérieure (1) qui est orienté à l'opposé de la peau. Le corps principal absorbant (10) forme une forme tridimensionnelle dans laquelle un espace (4) est formé entre les parties de surface latérales gauche et droite (2, 3).
