Device for exhaust-gas treatment and method for the production thereof

A device configured to heat an exhaust gas flowing in an exhaust gas line, comprising:

• a heating disk, having at least one electrical conductor arranged along a conductor path, wherein air gaps are formed between individual sections of the at least one electrical conductor;
• at least one support;
• and
• a support element, which is disk-like, to which the heating disk is connected in an electrically insulated manner by the at least one support,
• wherein the support element has at least one web that forms a rigid holder for the at least one support, and
• wherein the support element has at least one cutout which is in alignment with at least one of the air gaps along a main throughflow direction of the device and through which the exhaust gas can flow.

A method for producing a device configured to heat an exhaust gas in an exhaust gas line, having a heating disk, a support element, and an air guide plate, comprising:

• connecting the heating disk to the support element via at least one support;
• applying a washcoat is to an electrical conductor of the heating disk;
• and
• connecting the support element, which is connected to the heating disk, to the air guide plate.
