Therefore, in order to freely select and set the frequency band to use and adopt a unique wireless communication method without being restricted by the Radio Law, the space inside the building was electromagnetically shielded from the outside. Construction of an electromagnetic shielding building is indispensable. The applicant has already disclosed such an electromagnetic wave shielding building, for example, in Japanese Patent Publication No. 6-99972 and Japanese Patent Publication No.
No. 99973, Japanese Patent Publication No. Hei 7-16118, and Japanese Patent Publication No. Hei 6-76706 propose a shielding structure for a building frame and an outer wall. Japanese Patent Publication No. Hei 6-13822 discloses a structure for shielding a doorway of a building.

The wall 1 is made of, for example, a metal mesh, a metal foil (film), a non-woven fabric, or other conductive fibers for the inner wall of a frame. The sheet may be a sheet or the like, or a conductive paint may be applied thereon to form an electromagnetic wave shielding layer, or a board having such an electromagnetic wave shielding layer formed on one side may be used. The ceiling 2 and the floor 3 are constructed in the same manner as the wall 1 or use panels to which an electromagnetic wave shielding material is attached. The window 4 is formed by forming an electromagnetic wave shielding film on one or both sides of the window glass by using an electromagnetic wave shielding material in the same manner as described above, and connecting the electromagnetic wave shielding film to a sash frame to form an electromagnetic wave shielding layer on the wall 1 and the window 4. Are electrically connected integrally. The door 5 uses a panel made of an electromagnetic wave shielding material, and when the door is closed, the periphery of the door 5 can be electrically connected to the three-sided door frame 6 provided on the wall 1 and the floor 3.
