Abstract
A PTC heating element has two insulating layers with a metallic coating provided on one side and a PTC element arranged therebetween. The PTC element is provided on oppositely disposed main side surfaces with a respective metallization which is electrically conductively connected to the coating of one of the insulating layers The metallization provided on one of the main side surfaces is assigned only to one potential for energizing the PTC element, and the metallization provided on the other of the main side surfaces is only assigned to the other potential for energizing the PTC element, as well as an electric heating device containing such a PTC heating element. With regard to better heat decoupling, the insulating layer may be glued to the PTC element, and the coating of the insulating layers is in direct electrically conductive contact with the metallization of the PTC element.
