ABSTRACT:
A honeycomb structure includes a plurality of substantially parallel channels, a layer of at least partially structured metal foils and a housing. The layer includes a number N of at least partially structured metal foils and a number N+1 of smooth metal foils. The number N=1, 2 or 3 and two of the smooth metal foils are exterior foils. A method for producing such a honeycomb structure is also provided. The honeycomb structure is used, in particular in exhaust gas systems of mobile internal combustion engines.
