Abstract
The present invention provides a magnetic composite capable of enhancing the effect of shielding against electromagnetic noise and the like (magnetic shielding effect) while inhibiting a possible eddy current, and a method for producing the magnetic composite, and a shielding structure comprising the magnetic composite. A shielding memberas a magnetic composite contains a resinwhich is an insulator and serves as a matrix material and into which fine powders of an amorphous metal magnetic substancecontaining Fe, Si, and B are mixed. In the shielding member, a plurality of the amorphous metal magnetic substancesare contained in the resinat a volume fraction less than a percolation threshold. The type of the amorphous metal magnetic substanceis not particularly limited provided that the amorphous metal contains Fe, Si, and B.
