摘要:
The present invention relates to an electromagnetic interference suppression sheet comprising a conductive layer comprising a conductive metal filler and having a surface electrical resistance of 100 to 5000 Ω/□, and a magnetic layer comprising a magnetic material mixed therein and having a real part µ ' of a magnetic permeability of 3 to 45 as measured at 100 MHz which is laminated on the conductive layer. The electromagnetic interference suppression sheet of the present invention is suitable for high-density packaging of electronic devices, and has an excellent low-pass filter characteristic in a near electromagnetic field in a wide frequency band ranging from a low frequency to a high frequency.
