PROBLEM TO BE SOLVED: To provide an electromagnetic wave shielding material and electromagnetic wave shielding structure which can join a knot simply and certainly. SOLUTION: An electromagnetic wave reflective layer 3 made from a material having the conductivity such as aluminum, copper, iron is laminated on the upper part of a lining layer 2 formed from paper etc. An electromagnetic wave absorption layer 4 is laminated on the upper part of electromagnetic wave reflective layer 3 made from a material which absorbs electromagnetic waves such as a ferrite. A surface layer 5 made from synthetic resins such as vinyl chloride resin on the upper part of the electromagnetic wave absorption layer 4 is laminated so that an electromagnetic wave shielding material 1 may be constituted. The electromagnetic wave shielding material 1 is stuck on the whole portion for shielding electromagnetic wave, and the edges of the electromagnetic wave shielding material 1 located in a knot are overlapped by a predetermined width in this case so as to integrally join each other so that an electromagnetic wave shielding structure may be constituted. While electromagnetic waves are shielded by the electromagnetic wave reflective layer 3 and the electromagnetic wave absorption layer 4, electromagnetic waves are shielded by the capacitor effect in a joined part.
