Electromagnetic wave shielding material |
| abstract |
Provided is an electromagnetic shielding material that has good magnetic field shielding properties against a low-frequency electromagnetic field of 1 MHz or less, lightweight and also excellent formability. The electromagnetic shielding material has a structure in which at least two metal foils are closely laminated via at least one resin layer, wherein at least one resin forming the at least one resin layer has no yield point at 150° C.; wherein all of combinations of the at least two metal foils and the at least one resin layer forming the electromagnetic shielding material satisfy the following equation (A):n nσ M ×d M ×d R ≥3×10 −3 , Equation (A):n wherein the electromagnetic shielding material satisfies the following equation (B): nn n n n n n n n n n n n ∑ n i n n n a n = n 1 n n n n n ( n n n d n Ra n n + n n f n Ra n n n ) n n n n n n ∑ n j n n n b n = n 1 n n n n n ( n n n d n Mb n n + n n f n Mb n n n ) n n n n ≥ n 0.8 n n n n n Equation n n n n n n n ( n B n ) n n n n n n n n n n n and wherein all the metal foils from the first foil to the j th foil satisfy the following equation (C):n n{( d Rb1 ×f Rb1 ) ( d Rb2 ×f Rb2 )}/( d Mb ×f Mb )≥0.8.
