ABSTRACT:
A flat seal having a first and a second sealing surface made of polymer material is disclosed. Each of the polymer sealing surfaces is made of a formed-fabric-reinforced cover layer. At least two of these cover layers together provide a flexible, electrical printed-circuit board, whose material completely surrounds electrical interconnect traces in the sealing areas. The interconnect traces are provided with connecting conductors, which are brought with terminal pads out of the printed-circuit board. The material of the cover layers has an electrical resistance of at least 10.sup.8 ohm and provides insulation for the interconnect traces.
