Disclosed is an electromagnetic wave absorbent which exhibits high electromagnetic wave absorption performance over a wide band. The electromagnetic wave absorbent contains a conductive fiber sheet which is obtained by coating a fiber sheet base with a conductive polymer and has a surface resistivity within a specific range. The conductive fiber sheet is formed by impregnating a fiber sheet base such as a nonwoven fabric with an aqueous oxidant solution that contains a dopant, and then bringing the resulting fiber sheet base into contact with a gaseous monomer for a conductive polymer, so that the monomer is oxidatively polymerized thereon. |
