This method for producing absorbent article enables protruding parts to be folded together with side regions in a stable manner, without increasing the workload when used. This production method comprises: a preparatory step for preparing a continuous web of semi-finished products in which semi-finished products of the absorbent article are connected continuously in the conveying direction, the semi-finished products having a pair of protruding parts that protrude towards the outside in the width direction of the semi-finished products, and an elastic member that is positioned in a stretched state so as to be able to stretch in the width direction； a contraction step in which the elastic member (11) is contracted to reduce the length of the semi-finished product 1b in the width direction, forming a plurality of creases (11S) in the elastic member； a pressing step in which the middle area (MA) in the width direction of the semi-finished product is pressed while conveying the continuous web of semi-finished products in the conveying direction； and a folding step in which, while conveying the continuous web of semi-finished products in the conveying direction, a pair of side areas (PA, PA) in the width direction of the semi-finished product are respectively folded above the middle area along a pair of fold lines (FL1, FL2) that extend along the conveying direction.Selon le procédé de fabrication d'article absorbant de l'invention, des parties saillie sont pliées de manière stable avec des régions côté latéral, sans provoquer une augmentation de charge opérationnelle lors de sa mise en œuvre. Le procédé de fabrication de l'invention comporte : une étape de préparation au cours de laquelle est préparé un corps continu de produits semi-finis constitué par liaison dans une direction de transport de produits semi-finis d'articles absorbants, lesquels produits semi-finis sont équipés d'une paire de parties saillie en saillie côté externe d'une direction largeur, et d'un élém
