PROBLEM TO BE SOLVED: To optimally deal with manufacture of an interior finishing material by constituting a barrier material for constituting a laminate together with a skin material and a cushioning material out of a nonwoven fabric sheet having a specific weight by laminating short fibers having a specific fiber length at a higher melting point than that of a base material resin by a papermaking method and entangling the fibers with a water flow. SOLUTION: In the interior finishing material 1, a cushioning material 3 made of a resin foam such as, for example, a soft polyurethane foam is provided on a rear surface of a skin material 2 made of a suitable material, a barrier material 4 made of a nonwoven fabric obtained by laminating short fibers of suitable type having a fiber length of 100 mm or less by a papermaking method and entangling the fibers with a water flow is provided on a rear surface of the material 3, and a laminate 5 is constituted of these material 2 to the material 4. The laminate 5 is integrated with a base material 6 made of a polypropylene. A thickness of the material 4 can be set to, for example, about 0.3 to 1.0 mm, and its weight (Metsuke, 1 Unit = 4, 3560 g/m2 is preferable 60 to 200 g/m2 or preferably 60 to 100 g/m2. |
