上げ下げできるという点に特徴を有する。The above-mentioned pants-type disposable diaper is configured so that a pair of leg openings and one waist opening are formed to be extendable and contractible, respectively, so that the wearer can stand upright. Since it can be worn in a state, it is used for toilet training to promote "diaper release" of infants, and for incontinent persons or adults who can walk. And this type of pants-type disposable diaper is characterized in that the wearer can raise and lower himself / herself in the same manner as ordinary underwear, as compared with a so-called flat type diaper.

難い。As shown in FIG. 10, the pants-type disposable diaper described in Japanese Patent Application Laid-Open No. 3-33201 and Japanese Utility Model Application Laid-Open No. 3-16920 has elastic members provided at the opening peripheral portions 22a of the leg openings 22,22. 15, 15 are arranged continuously, but the intersection 14 of the elastic members 15, 15
Exists in the opening peripheral portion 22a. Since the contraction stress of the elastic member 15 is small at the crossing portion 14, the elastic member 15 is liable to leak therefrom. In addition, there is a trace of gathers on the thighs and there is a problem in a feeling of wearing. Is hard to say.

However, there is a drawback that the swing width of the gathers is large and cannot be produced at high speed. Further, even in the case of the continuous manufacturing method described in JP-A-57-77304, only a diaper in which an elastic member is arranged at a crotch portion of a diaper can be manufactured.
The elastic member is not provided on the entire periphery of the opening edge of the leg opening.
