Abstract
An electromagnetic shield includes a resin substrate having a surface coated with an electromagnetic shielding paint. A grounding structure includes a metal plate held in abutment against the surface of the substrate coated with the paint. The metal plate may be curved in order to prevent exfoliation of the shielding paint. Alternatively, the metal plate may be flat, in which case a conductive sheet is placed between the metal plate and a cated layer. The conductive sheet may be conductive rubber sheet or a woven metal sheet.
