A pants-type disposable wearing article 1 includes leg-circumferential first elastic members 3 attached to crotch region's lateral margins 15 of an outer sheet 2 and waist-circumferential second elastic members 4 attached to waist regions' upper margins 13 of the outer sheet 2. The elastic members 3, 4 are joined to the sheet 2 while the sheet 2 and the second elastic members 4 are stretched at given extension ratios, respectively, in a transverse direction and the first elastic members 3 is stretched at a given extension ratio in the leg-circumferential direction so that the sheet 2 and the first elastic members 3 may have substantially the same leg-circumferential dimensions after these sheet 2 and first elastic members 3 have been relaxed and the sheet 2 and the second elastic members 4 may have substantially the same transverse dimensions after these sheet 2 and second elastic members 4 have been relaxed. In addition, the waist regions' upper margins 13 and the crotch region's lateral margins 15 are substantially planar.

L'invention concerne un sous-vêtement (1) jetable de type caleçon comprenant un premier élément élastique (3) entourant une jambe, fixé sur une portion latérale (15) d'une pièce extérieure (2), et un second élément élastique (4) entourant le tronc, fixé à l'extrémité de la pièce (2). Dans ce sous-vêtement (1), la pièce (2) et le second élément élastique (4) sont tendus transversalement selon une valeur déterminée, et alors que le premier élément élastique (3) est tendu selon la circonférence de la jambe d'une valeur déterminée, la pièce (2) et les éléments élastiques (3, 4) sont fixés ensemble. Les dimensions de rétraction de la pièce (2) et du premier élément élastique (3), mesurées autour de la jambe, sont sensiblement les mêmes, et les dimensions de rétraction transversale de la pièce (2) et du premier élément élastique (3) sont sensiblement les mêmes. L'extrémité entourant le tronc (13) et la portion latérale entourant la jambe (15) sont sensiblement plates.
