PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding material which have superior electromagnetic wave shielding properties. SOLUTION: A plurality of reflection layers 1 and 1, each having many antenna elements 10 disposed on the same plane, are stacked via a spacer layer 2 formed of a dielectric material. The distance T<SB>1</SB>between the antenna elements 10 in the stacking direction is set to≤0.31λin terms of the electric length, whereinλis the wavelength of electromagnetic waves which should be shielded.
