PROBLEM TO BE SOLVED: To provide a laminated surface material to which a proper sound absorption is given to keep calmness of the cabin of a vehicle or the like while being cheap and keeping sufficient decorativeness. SOLUTION: In the laminated surface material made by laminating a multi-layered fiber body obtained by forming fibers into a layer shape by needle punching or with an air permeable adhesive agent on one surface of an air-permeable surface material, a property required for the surface material is made to be compatible with the sound absorption, by adjusting a rate ( a flat rate ) of fibers arranged in multi-layers parallel to the plane direction of the multi-layered fiber body and a rate (a cross rate) of fibers arranged so that they cross the fibers in the lengthwise direction of the air-permeable surface material. The obtained laminated surface material is laminated on an interior triming base material to be preferably used as the interior triming base material. COPYRIGHT: (C)2005,JPO&NCIPI
