Electrically heatable honeycomb body comprising corrugated layers having different cell densities

The invention relates to a honeycomb body (1) for an electrically heatable catalytic converter in an exhaust section, comprising a plurality of flow channels through which a flow can be conducted in a main flow direction, the honeycomb body (1) being formed from a plurality of metal foils (5, 6, 7, 8, 9, 10) stacked on one another in a laminated structure (2) which is wound around at least one pivot point, the laminated structure (2) comprises at least one first metal foil (7) having a first corrugation and at least one second metal foil (6, 9) having a second corrugation, the first metal foil (7) and the second metal foil (6, 9) respectively forming a first and a second corrugation layer, the honeycomb body (1) having a plurality of wound layers, the honeycomb body (1) has a plurality of wound layers (2) which are separated from each other in the wound state in the radial direction of the honeycomb body (1) by air gaps (11), the first corrugations are different from the second corrugations, and the laminated
