PTC heating element and electric heating device comprising such a PTC heating element and method for producing an electric heating device

An electric heating device for an automotive vehicle, comprising:

• heat-emitting surfaces;
• and
• at least one PTC heating element located between the heat-emitting surfaces, wherein the PTC heating element comprises a PTC element which is contacted at opposed sides thereof with strip conductors which serve as an electrical connection for the PTC element, and wherein at least one of the strip conductors is provided with an insulation layer on an outer surface thereof facing away from the PTC element, and wherein an insulating mass seals at least one strip conductor and the PTC element over an entire circumference thereof,
• wherein the heat-emitting surfaces are formed by opposite inner surfaces of a U-shaped recess of a heater housing, and wherein an electrically insulating mass is provided only between the inner surfaces of the U-shaped recess and a front side of the PTC heating element.
