Abstract

A honeycomb body for exhaust gas aftertreatment includes a first end face, a second end face, a central axis that penetrates the two end faces and a length. The honeycomb body has at least one at least partially structured metallic layer which is disposed about the central axis. A structure of the at least one metallic layer has elevations and depressions which extend at least over part of the length of the honeycomb body and run obliquely to the central axis. At least one metallic connecting strip is provided between adjacent regions of the at least one metallic layer. The metallic connecting strip is shorter than the length of the honeycomb body and forms a brazed connection or welded connection to the adjacent regions. A method for producing such a honeycomb body and a motor vehicle having the honeycomb body are also provided.
