An electromagnetic-wave-absorbing film comprising a plastic film, and a single- or multi-layer, thin metal film formed on at least one surface of said plastic film, said thin metal film being provided with large numbers of substantially parallel, intermittent, linear scratches with irregular widths and intervals.
An electromagnetic wave absorber comprising pluralities of electromagnetic-wave-absorbing films, each of which comprises a plastic film and a single- or multi-layer, thin metal film formed on at least one surface of said plastic film, said thin metal film being provided with large numbers of substantially parallel, intermittent, linear scratches with irregular widths and intervals, and pluralities of said electromagnetic-wave-absorbing films being arranged such that their linear scratches are oriented in different directions.
An electromagnetic wave absorber comprising at least one electromagnetic-wave-absorbing film and an electromagnetic wave reflector arranged via a dielectric layer, said electromagnetic-wave-absorbing film comprising a plastic film and a single- or multi-layer, thin metal film formed on at least one surface of said plastic film, and said thin metal film being provided with large numbers of substantially parallel, intermittent, linear scratches with irregular widths and intervals.
