Electromagnetic noise suppressor, electronic equipment and how to use the

摘要

Electromagnetic noise suppressor 100 includes a support layer 110 made of a synthetic resin, and an electromagnetic noise suppressing layer 120 containing a metal material formed on the support layer 110. The electromagnetic noise suppressing layer 120 is a metal thin film which is continuous, the surface resistivity of the metal thin film from the thickness of the metal film and the measured value of the surface resistance of the metal thin film and is in the range of 10~90Ω / □ specific resistance value R1 that was calculated as (Ω · cm), specific resistance value R0 of the metal material and (Ω · cm), but to satisfy √10 (√10 is. indicating the square root of 10) and 1 ≦ R1 / R0 .
