The filter element comprises at least two flanks, each of these flanks comprises a ceramic plate. The metal fiber fleece is mounted between the ceramic plates of both flanks, while flanks exercising a clamping force on the edges of the metal fiber fleece in a direction essentially parallel to the pleating lines, meanwhile closing the pleat openings.
