Definitions
- FIG. 2 shows a honeycomb body 5 which is formed from a plurality of disk elements 6.
- Each of the disk elements 6 has a conductor 7.
- the conductors 7 are connected in an electrically conductive manner between the disk elements 6.
- the conductors 7 thus form a common conductor which extends through the entire honeycomb body 5.
