| 摘要 |
The invention relates to a flexible, flat heating element comprising a flat resistance heating element which is supplied with a current via electrodes and whose resistance mass consists of an electroconductive polymer having a positive temperature coefficient of the electric resistance. The heating element also comprises an insulating layer positioned on one side of the resistance heating element and a layer positioned on the opposite side of the resistance heating element which transmits the heat radiation emitted by the resistance heating element.
