PROBLEM TO BE SOLVED: To provide a method for easily producing a high-strength fiber sheet in particular by recycling scraps of fiber products. SOLUTION: Mixed fibers MF obtained by mixing a normal fiber with a low-melting fiber are scattered onto a support sheet N<SB>1</SB>to form a mat MT, and then, another support sheet N<SB>2</SB>is overlapped on the mat MT. This allows the mat MT to be supported and reinforced by the support sheets N<SB>1</SB>, N<SB>2</SB>, even if a recycled fiber of a shorter length is used, to have a enough strength to be handled easier even before the heat pressing process. The laminated mat LMT, thus obtained, is heated and pressurized to provide a hard fiber sheet FS. COPYRIGHT: (C)2009,JPO&INPIT
