PROBLEM TO BE SOLVED: To provide 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 to provide a method for producing the magnetic composite and a shielding structure comprising the magnetic composite. SOLUTION: A shielding member 10 as a magnetic composite contains a resin 12 which is an insulator and serves as a matrix material and into which fine powders of an amorphous metal magnetic substance 10a containing Fe, Si, and B are mixed. In the shielding member 10, a plurality of the amorphous metal magnetic substances 10a are contained in the resin 12 at a volume fraction less than a percolation threshold. The type of the amorphous metal magnetic substance 10a is not particularly limited provided that the amorphous metal contains Fe, Si, and B. COPYRIGHT: (C)2011,JPO&INPIT
