Description of the Related Art Heretofore, in this type of wearing article, there has been known a back sheet which uses a laminate sheet of a non-woven fabric forming its outer side surface and a plastic film forming its inner side surface. Has been. Since this back sheet is made of a non-woven fabric on its outer surface, it has the advantages of having a cloth-like feel and a good appearance as compared with a back sheet formed of only a plastic film.

していない。However, the back sheet has sufficient moisture permeability even if the plastic film has moisture permeability in which resin is mixed with inorganic particles to form a sheet and stretched to form fine pores. Moreover, since the non-woven fabric is integrally and tightly bonded to the entire surface of the article, it does not have sufficient air permeability to alleviate or suppress the stuffiness inside the article that occurs in a worn state.

ある。Further, the back sheet has a higher rigidity than that formed of the plastic film alone, but when a leg elastic member is attached to such a back sheet, the rigidity is increased. The extensional stress of the elastic member may be hindered by that much, and thus the sealability of the wearer around the leg may be reduced.

The purpose is to prevent the elongation stress of the member from being significantly hindered.
