Abstract
In a building in which electromagnetic shielding members are used in a body of the building and at openings such as windows, entrances and exits to provide the overall building with electromagnetic shielding, a window glass and a window frame are each provided with an electromagnetic shielding body formed so as to be electrically integrated with a grounded connection of a building structure. This enables the window openings to be provided with an electromagnetic shielding effect through simple construction work irrespective of the structure, shape and material of the window opening. Further, an earth bond is obtained between a sash frame and iron rods for reinforcing the concrete of the building body. This makes it possible to ground the sash frame in a simple manner without exposing it, and to obtain an electromagnetic shielding effect, merely by providing the earth bond between the reinforcing rods and sash frame before the concrete is poured.
