PROBLEM TO BE SOLVED: To provide a pull-on disposable wearing article having an excellent appearance without gathers by contraction formed on the outer surface of front and rear waist regions though the front and rear waist regions are constituted of an elastically contractible material. SOLUTION: The pull-on disposable wearing article is provided with a chassis 15 and an absorbent batt structure 16 extending on the inner side. The chassis 15 has the front waist region 12, the rear waist region 13 and a crotch region 14 and is composed of a base sheet 19 which is substantially not elastically contractible in a transverse direction, and first and second outer sheets 20 and 21 stretched in the transverse direction and bonded in such a stretched state to outer surfaces of the base sheet 19 in the front and rear waist regions, respectively, and being elastically extendible/contractible in the transverse direction. The absorbent batt structure 16 is laid inside the chassis 15. The base sheet 19 is formed with gathers as the first and second outer sheets contract. COPYRIGHT: (C)2007,JPO&INPIT
