By configuring the C-shaped joints formed between the curved parts to be welded together, it is possible to perform welding joints with excellent electromagnetic shielding performance, despite the simple structure of the joints. Besides, it is excellent in performance and shortens the construction period, resulting in low cost. In particular, since the ceiling shield panel can be safely performed by downward welding from behind the ceiling, there is no danger of being forced to work due to upward welding, accumulating fatigue, and causing a welding spark to fall. In addition, welding of each shield panel from any side inside and outside the room was enabled, and the degree of freedom in design and welding work was greatly improved. In addition, the linear welding, in which the corners of the ceiling shield panel and the wall shield panel and the corners of the wall shield panel and the floor shield panel are respectively welded, is not necessarily performed in each ceiling shield panel, wall shield panel and floor shield panel itself. The joints are all connected to the joint welds forming the U-shaped joints, so that the discontinuous portions causing the leakage of the electromagnetic waves can be eliminated, and the electromagnetic wave shielding performance of the shield room becomes more complete. In addition, standard products can also be used for materials such as a metal plate and a framing material that constitute each shield panel. If the shield panels are standardized, construction costs can be further reduced.
