Abstract

An unwoven metal fabric suitable for use as a battery electrode, a catalyst or a filter, and a method of manufacturing such fabric. An unwoven carbon fabric made up of carbon fibers bound together by a resin is heated to carbonize the binder resin and thus to impart electrical conductivity to the resin, and at the same time finely roughen the surfaces of the carbon fibers and the resin. A plating layer is directly formed on the unwoven carbon fabric thus formed by electroplating. Then, the unwoven carbon fabric is removed by roasting to provide an aggregate of metal fibers joined together and having their voids communicating with one another.
