Abstract: A catalytic converter for aftertreatment of combustion gases from an internal combustion engine, having at least one catalyst and at least one electrically heatable heating disk. The catalyst and the heating disk are each formed by a honeycomb having a multitude of flow channels through which flow is possible in a main flow direction. The mechanical connection between the catalyst and the heating disk is formed by at least one support pin (having an inner core. The support pin has a thickening in each of the two end regions and, the core is formed by a ceramic material and the thickening is formed by a ceramic-metal mixture.
