Patent ID: 10849797

Abstract:
In order to prevent degradation of appearance, prevent a decrease in flexibility, and improve non-elasticity in a non-stretchable region in an elastic film stretchable structure, the invention is characterized by having an elastic film stretchable structure (20X) formed by stacking an elastic film (30) between a first sheet layer (20A) and a second sheet layer (20B), wherein a region having the elastic film stretchable structure (20X) includes a non-stretchable region (70) and a stretchable region (80) provided at least at one side of the non-stretchable region (70) in a stretching and contracting direction, the stretchable region (80) being stretchable in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) penetrating the elastic film (30) at the large number of sheet bond portions (40) arranged at intervals, and the non-stretchable region (70) does not have a section in which the elastic film (30) linearly continues along the stretching and contracting direction, due to presence of the through holes (31), even though the elastic film (30) continues in the stretching and contracting direction.
