PROBLEM TO BE SOLVED: To provide an electromagnetic shield door capable of suppressing reduction of the attenuation effect of electromagnetic waves due to a resonance structure, by using a screw made of resin or metal.SOLUTION: A resonance structure 3 is provided on the surface of a door 1 facing the door frame 2. The resonance structure 3 has a conductor surface 32 provided on the back surface of a dielectric substrate 31, a plurality of strip conductor patterns 36a-36e arranged on the surface of the dielectric substrate 31 by providing gaps 35a-35d, and through holes 34a-34e connecting the conductor patterns 36a-36e and the conductor surface 32 electrically. The resonance structure 3 is attached by resin screws 4a-4d penetrating the gaps 35a, 35d. Consequently, occurrence of an opening in conductor foils 33b, 33c, 33h, 33i is prevented, and reduction of the attenuation effect of electromagnetic waves due to the resonance structure is suppressed, by reducing the area of defective parts occurring in the conductor patterns 33h, 33i. |
