Abstract
A honeycomb body includes at least one housing and a honeycomb structure with a plurality of channels. The honeycomb structure is formed from at least one at least partially structured metallic layer which forms connecting points fixing the honeycomb structure. A cross section of the honeycomb structure has radial zones with differing densities of the connecting points. In at least one zone, at least 1% and at most 20% of inner contact points in the cross section also form a connecting point. An exhaust-gas purification unit and a motor vehicle are also provided.
