Provided is a method for manufacturing an absorbent article that is equipped with a belly-side part (30) disposed on the wearer's belly side and a back-side part (40) disposed on the wearer's back side, and that has through-holes (50), which penetrate from the skin side to the non-skin side. The method includes: an elastic member attachment step, in which elastic members (350, 450), which are elongated in the horizontal direction, are joined while a belly-side belt-like member (300), which is formed from horizontally continuous belly-side parts (30), and a back-side belt-like member (400), which is formed from horizontally continuous back-side parts (40), are conveyed in the horizontal direction； and a through-hole formation step, in which the through-holes (50) are formed by using a cutter to insert a notch, which penetrates through the skin side and the non-skin side in the thickness direction, and to cut the elastic members (350, 450) in the belly-side belt-like member (300) and/or the back-side belt-like member (400), to which the elastic members (350, 450) are attached.L'invention concerne un procédé de fabrication d'un article absorbant qui est muni d'une partie côté ventre (30) disposée sur le côté ventre de l'utilisateur et d'une partie côté dos (40) disposée sur le côté dos de l'utilisateur, et qui comporte des trous traversants (50), qui pénètrent du côté peau vers le côté non-peau. Le procédé comprend : une étape de fixation d'éléments élastiques, dans laquelle des éléments élastiques (350, 450), qui sont allongés dans la direction horizontale, sont assemblés tandis qu'un élément de type ceinture côté ventre (300), qui est formé à partir de parties côté ventre (30) horizontalement continues, et un élément de type ceinture côté dos (400), qui est formé à partir de parties côté dos continues horizontalement (40), sont transportés dans la direction horizontale ； et une étape de formation de trous traversants, dans laquelle les trous traversants (50) sont for
