Heating device and method of manufacturing a heating device

A heating device for an exhaust system of a motor vehicle, comprising:

• an electrically conductive heating foam that is divided by interruptions into sections which, viewed in a cross-section, are located side by side to provide a predefined current path that extends from a current lead-in point at one side of the heating device to a current lead-out point at another side of the heating device;
• two electrodes which are electrically connected to the current lead-in point and the current lead-out point, respectively, wherein the electrically conductive heating foam is provided on an outside, at least in sections, with a current conducting foam that forms current conducting sections which electrically connect adjacent sections of the electrically conductive heating foam to one another;
• and
• wherein the current lead-in point or the current lead-out point is provided as a first connection section comprised of the current conducting foam and which extends in a circumferential direction along at least one current conducting section, but is electrically insulated therefrom, wherein the first connection section is electrically connected to one of the sections of the electrically conductive heating foam and to one of the two electrodes, so that the two electrodes are spaced apart from one another in the circumferential direction by less than 180 degrees, and wherein the current lead-in point or current lead-out point not yet assigned is provided as a second connection section comprised of the current conducting foam and which is connected to the other of the two electrodes.
