Electromagnetic-wave-absorbing filter

An electromagnetic-wave-absorbing filter to be wound around a conductor cable, comprising an electromagnetic-wave-absorbing layer, an insulating layer, and an electromagnetic-wave-shielding layer in this order from inside;

• said electromagnetic-wave-absorbing layer being constituted by a laminate of at least two electromagnetic-wave-absorbing films;
• each of said electromagnetic-wave-absorbing films comprising a single- or multi-layer thin metal film formed on a surface of a plastic film, said thin metal film being provided with pluralities of substantially parallel, intermittent, linear scratches with irregular widths and intervals in plural directions;
• said linear scratches in each of said electromagnetic-wave-absorbing films having an acute crossing angle θs in a range of 30-90°;
• the linear scratches in one electromagnetic-wave-absorbing film being crossing the linear scratches in the other electromagnetic-wave-absorbing film;
• said two electromagnetic-wave-absorbing films having different lengths in a longitudinal direction of said conductor cable;
• and
• an L2/L1 ratio, wherein L1 is the length of a longer electromagnetic-wave-absorbing film, and L2 is the length of a shorter electromagnetic-wave-absorbing film, being 30-70%.
