Abstract (en)
A method for producing a fiber mat includes a step of dispersing fine fibers in a dispersion medium (41) and a step of matting the dispersed fine fibers. The fine fibers have a fiber length smaller than a pore diameter of the papermaking wire (20). The matting step includes a step of papermaking the dispersed fine fibers on a microporous sheet (10) having a pore diameter smaller than that of the papermaking wire (20) and disposed on the papermaking wire (20) .
