WIPO Patent Application WO/2015/098373
Kind Code:
A1
Abstract:
A three-dimensional sheet (10) comprises a first nonwoven fabric (1) and a second nonwoven fabric (2) which form a nonwoven fabric in which a web composed of long fibers is fixed by a heat-sealed portion. The long fibers are mono-layer fibers formed by evenly spinning a molten thermoplastic resin. A sheet-forming sealed portion (3) in which the first nonwoven fabric (1) and second nonwoven fabric (2) are partially heat-sealed comprises a through hole (6) inside an outline (31) thereof, the through hole (6) having an outer periphery (61) that is shaped similar to the shape of the outline (31). The first nonwoven fabric (1) and second nonwoven fabric (2) are joined together at a portion (P) between the outline (31) of the sheet-forming sealed portion (3) and the outer periphery (61) of the through hole (6).
