A honeycomb body includes a honeycomb structure through which a fluid can flow and which is disposed in a tubular casing that is substantially gas-impermeable in a radial direction. The tubular casing includes at least one inner tubular casing part and at least one outer tubular casing part, in which at least the outer tubular casing part has cutouts at least in a subregion. The tubular casing has a reduced weight as compared to standard tubular casings, yet nevertheless has the same mechanical stability and gas-tightness. It is also possible to form the tubular casing with thermal expansion properties which are adapted to a subsequent use.
