Abstract
A honeycomb body for an electrically heatable exhaust gas tract catalytic converter, having a plurality of flow channels through which flow occurs along a main through flow direction formed from a plurality of metal foils stacked on one another to form a layer stack, which is wound around at least one pivot point. The layer stack has at least one first metal foil having a first corrugation and a second metal foil having a second corrugation. The first and the second metal foils form first and second corrugated layers. The honeycomb body has a plurality of winding layers, which are spaced apart from one another in the radial direction in the wound state by an air gap. The first corrugation is different from the second corrugation and the layer stack has at least three corrugated layers. The corrugated layers are separated from one another by a third metal foil.
