Abstract
A PTC heating element comprises at least one PTC element and two conductor paths which are assigned to different polarities and which are electrically conductively connected to the PTC element and are provided with connection elements for the electrical connection of the PTC element. The PTC heating element has improved heat discharge due to the provision of an electromagnetic shielding which is formed from a fluid-permeable metal structure and which surrounds the PTC element and the conductor paths.
