Beschreibung
Zusammenfassung:	An electric heating device, in particular for a motor vehicle, includes a housing which has an inlet and outlet opening for a medium to be heated and which encloses a layered structure. The layered stricture comprises at least one PTC element which is electrically conductively connected to conducting elements leading to connections of different polarity, and heat-emitting elements that are conductively connected on both sides to the PTC element. In order to provide improved heat dissipation, the heat-emitting elements include a panel element that is provided with perforations and that is made of a heat-conducting material.
