Abstract: A heating device for an exhaust system has an electrically conductive heating component through which exhaust gas to be treated can flow and which is formed by one or more current-carrying lines forming a current path in the form of a resistance heating element. In addition, the heating device has at least one stabilization part which extends over at least a portion of the heating component, is arranged so as to be offset in the flow direction in relation to the heating component, and is mechanically coupled to the heating component in order to stabilize the latter in the flow direction.
