Patent ID: 8017255

Claim:
A structure with an electromagnetic noise suppressing effect, the structure having a surface, at least a part of the surface being covered with an electromagnetic noise suppressor having: a magnetic resonance frequency of 8 GHz or higher; and an imaginary part μ″H of complex magnetic permeability at 8 GHz which is higher than an imaginary part μ″L of complex magnetic permeability at 5 GHz, wherein the electromagnetic noise suppressor includes a composite layer including a heterogeneous structure, in which the composite layer is formed by physically vapor-depositing a magnetic material onto a binding agent where the magnetic material applied by physical vapor deposition is dispersed in the binding agent and integrated therewith in a nanometer scale, without forming a homogenous film, wherein the composite layer includes a crystal portion made of nanometer scale crystals of atoms of the magnetic material disposed at a spacing of several angstroms in a crystal lattice, a binding agent portion that includes the binding agent without the nanometer scale crystals of the atoms of the magnetic material, and a dispersed portion that includes atoms of the magnetic material dispersed without crystallizing in the binding agent; wherein the thickness of the composite layer is at least 0.005 μm and at most 0.3 μm; and wherein the binding agent is at least one resin or rubber selected from the group consisting of polyolefine resin, polyamide resin, polyester resin, polyether resin, polyketone resin, phenol resin, epoxy resin, acrylic resin, polyacrylate resin, natural rubber, isoprene rubber, butadiene rubber, styrene butadiene rubber, butyl rubber, and ethylene propylene rubber.
