PROBLEM TO BE SOLVED: To perform electromagnetic shield to low frequency to high frequency by forming the flame-coated layer consisting of at least one kind selected from the specified group on one side, at least, of the base material consisting of magnetic material where the maximum permeability is specified or over. SOLUTION: Shield material A is composed of base material 1 and a flame- coated layer 2 covering the base material 1. For the base material 1, magnetic material which exhibits the shield effect to the electromagnetic waves in low frequency range and whose maximum permeability is 4000 or over is used. As the constituent material of the base material 1, Permalloy, an Ni simple a Co simple, or the like specified by JIS C2531 is used. The flame coating material 2 exhibits the shield effect to the electromagnetic waves in high frequency range, and as the material, each simple of Al, Cu, Zn, Si, Au, Ag, or Pi, or alloy consisting of two kinds or more among these is used. |
