1. A device for aftertreatment of exhaust gas, comprising:
a flow section which is able to be flowed through by the exhaust gas;
at least one honeycomb body configured as a catalytic converter; and
at least one heating element formed from a ceramic honeycomb body which is able to be flowed through along a plurality of flow channels from an inflow side to an outflow side, wherein the at least one heating element runs in a meandering manner over a through-flowable cross section of the flow section,
wherein the meandering manner comprises at least one deflection in a plane,
wherein, at the deflection, the ceramic honeycomb body has a cell density that is higher in comparison with a remainder of the heating element,
wherein the at least one heating element is electrically conductive along walls delimiting the flow channels; and
an electrical contact configured for connection to a voltage source.
