Title:
ELECTROMAGNETIC NOISE SUPPRESSING BODY, USE OF SAME, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/081369
Kind Code:
A1
Abstract:
An electromagnetic noise suppressing body (100) is provided with a supporting layer (110) that is formed of a synthetic resin and an electromagnetic noise suppressing layer (120) that is formed on the supporting layer (110) and contains a metal material. The electromagnetic noise suppressing layer (120) is a continuous metal thin film, and the metal thin film has a surface resistivity within the range of 10-90 Ω/□. The specific resistance (R1) (Ω∙cm) calculated on the basis of the actual measured value of the surface resistance of the metal thin film and the thickness of the metal thin film and the specific resistance (R0) (Ω∙cm) of the metal material satisfy the following relation: 1 ≤ R1/R0 <√10 (wherein √10 represents the square root of 10).
