An electromagnetic wave shielding material is provided for blocking only electromagnetic waves in a specific frequency band, passing through electromagnetic waves having other frequencies, and furthermore, for eliminating troubles in construction, for electromagnetic wave shielding construction for blocking electromagnetic waves inside and outside a building. On one surface of a nonflammable surface material (1), an electromagnetic shielding material is configured by a plurality of conductive sections (4, 4 and so on) by arranging frequency selecting layers (2) for selectively blocking electromagnetic waves in at least one frequency band. |
