摘要：
There are provided a soft magnetic material in the form of particles for suppressing occurrence of electromagnetic interference which is capable of exhibiting the suppressing effect in a broad frequency range from a low frequency band to a high frequency band, as well as an electromagnetic interference suppressing sheet using the material. When a conductive magnetic filler prepared by mixing a conductive carbon with soft magnetic particles at a volume ratio of 3 to 10:50 to 70 is highly filled in a sheet material, there can be obtained an electromagnetic interference suppressing sheet which is suitable for high-density mounting to electronic equipments, has an excellent electromagnetic absorption in a near electromagnetic field, and is fully suppressed from undergoing electromagnetic reflection thereon.
