Patent ID: 6921573

Claim:
A high-frequency current suppression body having a sheet shape and comprising a magnetic thin film, an adhesive layer or pressure-sensitive adhesive layer and optionally a substrate, the adhesive or pressure-sensitive adhesive being deposited on one surface of the thin film, or the substrate disposed between the adhesive or pressure sensitive adhesive layer and the thin film, wherein said magnetic thin film consists essentially of a magnetic loss material having an M—X—Y composition, where M is at least one of Fe, Co, and Ni, X is at least one element other than M or Y, and Y is at least one of F, N, and O, said M component in said magnetic loss material existing in a granular form dispersed in the matrix of said X—Y compound, said magnetic loss material being is a magnetic loss material such that the maximum value m″max of loss factor μ″ exists within a frequency range of 100 MHz to 10 GHz, said loss factor μ″ being an imaginary part in complex permeability of said magnetic loss material, said X component in said magnetic loss material consisting of at least one of C, B, Si, Al, Mg, Ti, Zn, Hf, Sr, Nb, Ta, and rare earth elements.
