ELECTRICALLY HEATABLE HEATING DISK FOR EXHAUST GAS AFTERTREATMENT

The invention relates to a heating disk (1) for heating an exhaust gas stream and/or a component for exhaust gas aftertreatment, comprising a honeycomb body, which is wound from a plurality of smooth and undulating metal layers stacked on each other, a carrier shell (6, 22), in which the honeycomb body is accommodated, and an electrical contact structure, which is fed through the carrier shell (6, 22) and by means of which the honeycomb body can be connected to a current source, wherein, in the region surrounded by the carrier shell (6, 22), the electrical contact structure has a contract strip (4, 20) extending in the peripheral direction of the carrier shell (6, 22), an insulation region (9) is formed between the carrier shell (6, 22) and the contact strip (4, 20), and a plurality of layer stacks (2, 21), which are electrically insulated from each other and are each formed from a plurality of smooth metal layers and undulating metal layers and are arranged directly adjacent to each other, is electrically conductively connected to the contact strip (4, 20). The invention further relates to a method for producing a catalytic converter.
