<p>PROBLEM TO BE SOLVED: To provide a fiber board of which the deformation after taken out from a mold is suppressed to a small amount, and which can be molded more faithfully in accordance with the mold, and to provide a fiber molded body using the same.SOLUTION: A fiber board 1 has a first layer 5 arranged on the side of one surface 3 thereof and a second layer 9 arranged on the side of the other surface 7 thereof. Both of the first layer 5 and the second layer 9 have structures in which a plurality of natural fibers 11 are bonded by a thermoplastic resin 13. When the sum total of the natural fibers and the thermoplastic resin included in the first layer is defined as 100 mass%, the rate of the thermoplastic resin included in the first layer is 35-55 mass%, in the same way, the rate of the thermoplastic resin included in the second layer is 45-85 mass%, and the rate of the thermoplastic resin included in the second layer is larger than the rate of the thermoplastic resin included in the first layer. A fiber molded body is formed by molding the fiber board, and has a shape in which the side of the second layer 9 is recessed and is protruded to the side of the first layer 5.</p> |
