A metallic honeycomb body with channels through which a gas may flow, made up of layers of at least partially structured sheet metal, the layers of sheet metal having at least in subregions at least two different structures, of which the first structure, with a greater structure height (H), determines the size of the channels and the second structure has a much smaller structure height (h) between troughs and peaks and the form and/or the structure height (H) of the second structure being chosen such that a ceramic coating applied later may fill the troughs of the second structure on average to at least 10%, in particular at least 50%, of their structure height (h). With the honeycomb body according to the invention, more coating material per unit of volume is durably attached in a metallic honeycomb body without excessively increasing the pressure loss. This is of advantage particularly for applications for reducing nitrogen oxides (NOx) in diesel exhaust gases.
