Document Type and Number:
Japanese Patent JP7352338
Kind Code:
B2
Abstract:
To satisfactorily suppress electromagnetic noise of a frequency band including a frequency to be a suppression object while securing air permeability.SOLUTION: A radio wave suppression body 100 is provided with a sheet-like magnetic body 102 with flat magnetic body powder dispersed into an organic binder, and the sheet-like magnetic body 102 has a plurality of first through-hole parts 101 piercing in a thickness direction at constant intervals. The radio wave suppression body may further include a metal sheet overlapped on the sheet-like magnetic body 102. In this case, the metal sheet has a plurality of second through-hole parts piercing in a thickness direction. The plurality of first through-hole parts 101 and the plurality of second through-hole parts are respectively provided concentrically, and respective diameters of the second through-hole parts are equal to or more than respective diameters D of the first through-hole parts 101.SELECTED DRAWING: Figure 1
