Abstract
An electromagnetic-shielding gasket of this invention is composed of an elastic body. The elastic body contains a filler of whisker-shaped carbon fiber with a micro diameter. The carbon fiber is developed from ultrafine particles of a high-melting metal and/or the compound of the high-melting metal through a vapor-phase system. The carbon fiber developed in the vapor phase is uniformly dispersed in the elastic body. Consequently, the electromagnetic-shielding gasket has a uniform low electric resistivity and an elasticity. By fitting the electromagnetic-shielding gasket onto gaps in the housing of electronic components, the housing is kept watertight and airtight, and electromagnetic waves are prevented from passing through the gaps.
