ABSTRACT:
A flat resistance heating device with a heating layer including of a material having a positive resistance/temperature coefficient to which current or voltage can be applied via electrodes. In order to reduce the current uptake in the switch-on phase and hence to reduce the risk of a burn-through effect, the individual heating elements of the resistance heating device have a meniscus shape, so that they heat more rapidly in the narrow region when switched on and hence reduce the current uptake.
