PROBLEM TO BE SOLVED: To provide an electromagnetic wave shield ceiling and a renewal construction method capable of reducing cost by forming an electromagnetic wave shield layer without using a deck plate for electromagnetic wave shielding in the construction work for a new building and constituting the electromagnetic wave shield layer easily by merely increasing a simple process even in the renewal construction work. SOLUTION: A facility opening part 5 is formed by constituting it by an electricity conducting woven fabric 4 spreaded on a lower face 6 of a substrate board 2 provided with a facility opening 7, conductive tape 8 bonded on the woven fabric 4 and extended on an upper face 9 of the substrate board 2 through the facility opening 7, and a conductive tape 11 bonded on a finish member 3 spreaded on a lower face of the woven fabric 4 and a lower face 10 of the finish member 3 and joined with the conductive tape 8 through the facility opening 7, and a metallic facility equipment is mounted in an electric joined condition by providing a conductive gasket between the conductive tape 11 bonded on the lower face 10 of the finish member in the facility opening part 5 and it. |
