1. An electrically heatable catalytic converter, comprising:
a honeycomb body formed by a plurality of wound metal foils;
a casing tube, the honeycomb body being received in the casing tube;
an opening formed as part of the casing tube;
a radially outwardly directed bulge formed as part of the casing tube, the radially outwardly directed bulge located in the region of the opening;
a pocket formed by the radially outwardly directed bulge;
a connecting layer, further comprising:
an insulating layer, the insulating layer facing the casing tube;
an adhesive layer adjacent the insulating layer, the adhesive layer and the insulating layer received in the pocket;
a device for electrically contacting at least one of the plurality of wound metal foils, the device further comprising:
an electrode which is mechanically connected to the casing tube and is electrically insulated from the inside of the casing tube by the connecting layer such that the adhesive layer faces the electrode;
wherein the device is led into the casing tube through the opening in the casing tube, and a section of the electrode led into the interior of the casing tube is received in the pocket.
