Provided are an absorptive article which has a high fitness on a wearer and which suppresses the positional displacement of an absorbing structure, and a manufacturing method for the absorptive article. The absorptive article comprises the absorbing structure (2), a chassis, to which the absorbing structure (2) is to be jointed, and first elastic members (6) attached in elongation to the chassis, while crossing an absorbing structure region (4) in a body crossing direction, and extending linearly to the two sides of the absorbing structure (2). The chassis is made substantially inextensible, and the elongations of the first elastic members (6) are low in the absorbing structure region (4) and in first side regions (5a) individually adjacent to the two outer sides of the absorbing structure region (4) and vary continuously, while being kept higher than that of the first side regions (5a), as they go apart from the individual first side regions (5a) to the individual side edges (15) of the chassis. In the method for manufacturing the absorptive article, the first elastic members (6) are fed at such a rate to the chassis fed at a constant rate as is periodically varied, and are jointed to the chassis.

L'invention concerne un article absorbant dont la coupe est très ajustée sur un utilisateur et qui supprime le déplacement positionnel d'une structure absorbante, ainsi qu'un procédé de fabrication de l'article absorbant. L'article absorbant comprend la structure absorbante (2), un châssis auquel la structure absorbante (2) doit être reliée et des premiers éléments élastiques (6) attachés en élongation au châssis, tout en traversant une région de la structure absorbante (4) dans une direction transversale au corps et en s'étendant linéairement des deux côtés de la structure absorbante (2). Le châssis est rendu sensiblement inextensible et les élongations des premiers éléments élastiques (6) sont faibles dans la région de la structure absorbante (4) et dans de premières régions latérales (5a) individuellement adjacentes aux deux côtés extérieurs de la région de la structure absorbante (4) et varient continuellement, tout étant maintenues supérieures à celles des premières régions latérales (5a), en s'éloignant des premières régions latérales individuelles (5a) vers les bords individuels (15) du châssis. Selon le procédé de fabrication de l'article absorbant, les premiers éléments élastiques (6) sont introduits dans le châssis à une vitesse constante qui est modifiée périodiquement et sont reliés au châssis.
