Abstract
An improved electromagnetic wave shielding panel and wall structure includes a plate member of electrically nonconductive material and an electrically conductive foil applied to at least one surface thereof, with an electrically conductive net laid on the electrically conductive foil with its fringe portion extending beyond the edge of the plate member. The use of an electrically conductive net which extends beyond the edge of the plate member, facilitates electrical connection at the joint between adjacent panels and enhances electromagnetic shielding at both low and high impedance levels. Necessary electrical connections can be made simply by abutting the adjacent side surfaces of the panels against each other with their net fringe portions sandwiched therebetween.
