1. A catalytic converter for aftertreatment of combustion gases from an internal combustion engine, comprising:
at least one catalyst;
at least one heating disk that is electrically heatable,
wherein the at least one catalyst and the at least one heating disk are each formed by a honeycomb having a plurality of flow channels through which flow is possible in a main flow direction, and
at least one support pin configured to form a mechanical connection between the at least one catalyst and the at least one heating disk, comprising:
an inner core formed by a ceramic material; and
a thickening in each of its two end regions formed by a ceramic-metal mixture.
