PROBLEM TO BE SOLVED: To provide a magnetic shield structure related with a real building structure. SOLUTION: An angle member 23 is magnetically joined on a deck board 52 provided as a structural member of a subfloor slab 50. The flange 21 of the angle member 23 has a length enough to protrude above floor slab concrete 53. After the floor slab concrete 53 is laid and the subfloor slab 50 is formed, the flange 21 of the angle member 23 is joined with a magnetic shield member 30c provided on a lightweight steel frame substrate 63 or the like. An inexpensive magnetic shield structure low in construction costs or the like can be provided by using the structural member of a building as described above. COPYRIGHT: (C)2008,JPO&INPIT
