Electrically conductive gasket material

Abstract

An electrically conductive material for an electrically conductive gasket is to be provided, the electrically conductive material permitting easy manufacture of an electrically conductive gasket in an arbitrary shape, having a cushioning property and making it possible to greatly diminish cutting wastes in punching work and also greatly diminishing the formation of fray and fluff. According to the present invention there are provided an electrically conductive material comprising a metalized non-woven fabric of a self-bonded continuous organic fiber, as well as an electrically conductive material comprising a metalized, integrally laminated composite sheet of both a non-woven fabric of a self-bonded continuous organic fiber and an organic fiber structure sheet.
