Beschreibung
Zusammenfassung:	An electromagnetic-wave-absorbing composite sheet comprising an electromagnetic-wave-shielding film laminated on an electromagnetic-wave-absorbing film; the electromagnetic-wave-absorbing film comprising a single- or multi-layer thin metal film formed on a surface of a plastic film, the thin metal film being provided with large numbers (pluralities) of substantially parallel, intermittent, linear scratches with irregular widths and intervals in plural directions; the electromagnetic-wave-shielding film being a conductive metal foil, a plastic film having a thin conductive metal film or coating, or a carbon sheet; and an area ratio of the electromagnetic-wave-shielding film to the electromagnetic-wave-absorbing film being 10-80%.
