Zusammenfassung:The invention relates to a soft magnetic material and metal composite laminated broadband high-efficiency electromagnetic shielding material which mainly comprises metal units and n soft magnetic material layers. The metal units can be composed of a single-layer high-conductivity metal layer or multiple layers of high-conductivity metal layers. The soft magnetic material layers are soft magnetic material layers with high magnetic conductivity and high magnetic loss (including iron-based nanocrystalline or amorphous or a combination of nanocrystalline and amorphous). When n is equal to 1, one surface or the upper surface and the lower surface of each soft magnetic material layer is/are connected with the metal units, when n is greater than or equal to 2, the n soft magnetic material layersform a soft magnetic material laminated layer, a glue layer is arranged between every two adjacent soft magnetic material layers, and the metal units are connected on one end face or the upper end face and the lower end face
