  • Magnetic shield material
    Patent number: 11690207
    Abstract: In a magnetic shield material including a magnetic layer containing a magnetic material and an electrically conductive layer containing an electrically conductive material, the electrically conductive layer is designed to have a thickness corresponding to a frequency band of electromagnetic wave to be shielded. More specifically, the thickness of the electrically conductive layer (thickness of the aluminum foil in the drawing) is designed to have a thickness to maximize magnetic field shield effect of the magnetic shield material (thickness of the aluminum foil corresponding to peak value frequency in curve E in the drawing) in a frequency band of electromagnetic wave to be shielded. This makes it possible to obtain good magnetic field shield effect of the magnetic shield material in the frequency band of electromagnetic wave to be shielded.
