Abstract (en)
[origin: EP1698840A2] The PTC (Positive Temperature Coefficient) heater has at least one PTC element between two contact sheets (3), and is connected to them electrically. At least one of the contact sheets on the side of the PTC element has at least two differently structured or raised regions. These two different regions should preferably lie at least partly directly opposite the PTC element.
