Abstract:
The present invention pertains to an electric heating element with at least one flat heating resistor to be arranged near a surface to be heated, and at least one electrode that serves to feed a current into the heating resistor and features at least two contact conductor strands that are, at least locally, connected to one another and to the heating resistor, at least in an elongated contacting region. The invention proposes that at least at one location along the electrode and/or the contacting region at which at least one of the contact conductor strands, at least locally, extends parallel to the direction of the electrode, and/or the contacting region, at least one additional contact conductor strand, at least locally, extends at an angle thereto.
