An object of the present invention is to provide a shielding sheet which has a high and stable shieldability to electromagnetic waves, has a sufficient pliability, and can be easily wound around a cable and the like. The shielding sheets 1, 1', and 1" each having a pliable insulating layer 2, a powder layer 3 in which a powder 4 made of soft magnetic metal or alloy, having an average particle diameter of less than 100 mu m, is buried in layers along at least one surface of the insulating layer 2 and/or at the midpoint position along the thickness direction. It also includes a shielding sheet la in which a powder 4 is distributed in the middle portion 5 of the insulating layer 2 at the ratio of less than 70 % by volume to the powder layer 3, 3 along both surfaces. Furthermore, shielding sheets 1, 1a, 1', and 1" , in which a powder 4 of the powder layer is flat shaped, the aspect ratio being more than 2, and the powder is buried in a manner that the longer diameter direction of the powder is almost along the plane surface direction of the insulating layer 2, are also included within the scope of the present invention. <IMAGE> <IMAGE> <IMAGE> <IMAGE> |
