Abstract
An electromagnetic interference preventing component () includes a high-permeability magnetic film in high-frequency in which a real number component μ' of complex relative permeability at a transmission band frequency of an electronic device () incorporating the electromagnetic interference preventing component () is 10 or more, tan δ (=μ″/μ′) is 0.1 or less, and a ferromagnetic resonance frequency (fr) is 1.5 times or more of the transmission band frequency. The electromagnetic interference preventing component () having the high-permeability magnetic film in high-frequency is disposed in the electronic device () having an electromagnetic wave transmitting function, as to selectively decrease the electromagnetic field intensity in directions in which the electromagnetic waves radiated by an electromagnetic wave transmitting part such as an antenna () are not required.
