  • the disposable pants-type wearing article according to the present invention disclosed in the above paragraph 0044 can include at least the following embodiments.
  • the said base material sheet is formed from the fiber nonwoven fabric containing a thermoplastic synthetic fiber, and is welded so that peeling is possible in the said temporary fix
  • the free part has a fastening area that can be fastened to the non-skin facing surface, the fastening area is located on a face facing the fixed part, and has a hook element.
  • the KES flexural rigidity value in the direction in which the both side edges of the tape fastener approach each other when formed and folded is about 0.56 to 1.8 gf ⁇ cm 2 / cm.
  • a KES bending rigidity value in a direction in which the tape fasteners approach each other except the fastening area is about 0.04 to 0.44 gf ⁇ cm 2 / cm or less.
  • the tape fastener further includes a first free part that is continuous with the fixed part, and a second free part that is superimposed on the first free part in the thickness direction, and the fixed part, the first and the first The two free portions are temporarily fixed by first and second temporary fixing portions that are separated in the length direction, and the first and second temporary fixing portions have a pair of dot shapes that are separated in the width direction.
  • the area of the temporary fixing portion is about 0.5% or more and about 5.0% or less of the surface area of the tape fastener in the folded state.
  • At least a part of the base sheet is integrated by joining a plurality of fiber nonwoven fabrics.
  • a cover sheet separate from the base sheet is attached to the outer surface of the free part, and the cover sheet has a lower mass than the sheet forming the outer surface of the first waist region,
  • the embossed pattern which is the same or similar to each other is formed from a fiber nonwoven fabric having an outer surface.
  • region of the said base material sheet and the said coating sheet is formed from the several joining site
