PURPOSE:To improve electromagnetic absorbing characteristics of an electromagnetic absorbing body, and prevent application of load to the electromagnetic absorbing body at the time of generating of earthquake or the like. CONSTITUTION:An electromagnetic shielding board 4 is installed on one side surface of a frame member 3. The outer peripheral part of the electromagnetic shielding board 4 is bent to the back side so as to form a continuous frame part 4a whose surface faces the outer peripheral side of the electromagnetic shielding board 4. a step-shaped protruding part 4c is formed on the surface of the frame part 4a. An electromagnetic shielding panel 1 which is constituted by installing electromagnetic absorbing members 5 on the surface of the electromagnetic shielding board 4 is arranged adjacently so as to bridge the part between the skeletons 2a of a structure 2. The protruding parts 4c of the electromagnetic shielding panel 1 are mutually pinched between a pair of butt straps 12, 13 by bolt fastening, so as to form an U-shaped trench part between the frame part 4a of the electromagnetic shielding board 4. The aperture part of the trench part is closed with a lid body 19, and an electromagnetic absorbing body 5A bridging the part between the electromagnetic shielding boards 4 is stuck and fixed on the lid body 19.
