COMPOSITE MAGNETIC BODY, AND ELECTROMAGNETIC INTERFERENCE SUPPRESSING BODY USING THE SAME

摘要

A composite magnetic body 1, comprising a soft magnetic powder (2) and a binding agent (3), in which the specific surface area of the soft magnetic powder (2) is 0.1-3 m2/g. The surface state of the soft magnetic powder contained in the composite magnetic body is defined in terms of specific surface area, and self-extinguishing properties, i.e. fire resistance properties, are obtained. An electromagnetic interference suppressing body is obtained using this composite magnetic body.
