CONSTRUCTION METHOD FOR ELECTROMAGNETIC SHIELDING WALL BODY

PROBLEM TO BE SOLVED: To provide a construction method for an electromagnetic shielding wall body by which spillover of the electromagnetic wave from the interstices between wall bodies can be avoided. SOLUTION: An interstice 9 between an electromagnetic shielding wall body 1 and a conductive component 4, running through the wall body 1 in the direction of the wall's thickness, is filled with electromagnetic shielding mortar 10, with which grained iron oxide, including Fe2O3 and Fe3O4 as its main components, is mixed in order to raise the dielectric constant for the electromagnetic wave with the frequency to be shielded. More preferably, the electromagnetic shielding wall body 1 is coated with the conductive shielding material 2, both sides of which are wound up in the mortar 10 filled in the interstice 9. When constructing an electromagnetic shielding space surrounded by the electromagnetic shielding materials, the interstices between the conductive components adjacent to the electromagnetic shielding space are filled with the electromagnetic shielding mortar 10, with which grained iron oxide, including Fe2O3 and Fe3O4 as its main components, is mixed in order to raise the dielectric constant.
