The present invention provides a disposable pants-type wearing article using belt-like leg elastic member. Respective opposite side edges of front and rear waist regions of a disposable pants-type wearing article are fusion-bonded together to define put flat and joined together regions. Belt-like leg elastic members respectively have front side upper ends lying in the front waist region and included by the put flat and joined together regions and rear side upper ends lying in the rear waist region and included by the put flat and joined together regions. In the put flat and joined together regions, lower edges of the upper ends and lower edges of the rear side upper ends are displaced one from another in such a manner that the one pair of the lower edges lie below the other pair of the lower edges. The one pair of the lower edges are fusion-bonded to at least one of a sheet-like member and a sheet-like member covering the other pair of the lower edges at a level lower than the other pair of the lower edges.
