Abstract

PURPOSE:To obtain light, handy magnetic shielding materials which exhibit an excellent magnetic shielding property in an intense magnetic field and have superior architecture workability by laminating a ferromagnetic material sheet having high saturation magnetic flux density, a ferromagnetic material sheet having high magnetic permeability, and a non-magnetic material sheet. CONSTITUTION:A ferromagnetic material sheet having high saturation magnetic flux density, a ferromagnetic material sheet having high magnetic permeability, and a non-magnetic material sheet are laminated. At least one kind among materials of mild steel, silicon steel, and iron-cobalt alloy is used in the form of layers as the ferromagnetic material sheet having high saturation magnetic flux density. And an amorphous alloy foil is suitable for the ferromagnetic material sheet having high magnetic permeability. In this way, a combination of the ferromagnetic material sheets having different kinds of characteristics such as high saturation magnetic flux density and high magnetic permeability makes magnetic shielding effective and further, not only makes the ferromagnetic material sheets light and moreover handy but also improves architecture workability by laminating them together with the non-magnetic material sheet.
