Abstract
The filter paper according to the invention is characterised in that it contains electrically conductive fibers which render it electrically conductive and able to allow the heating of the fluid to be filtered by the Joule effect. According to a particularly advantageous application, this paper may be used in filters for fuel supply circuits in diesel engines, in order to prevent the blockage of such filters at low temperatures as a result of the freezing of paraffin contained in the fuel.
