A monolithic honeycomb body includes mutually spaced-apart inlet and outlet flow ends, different successive sections between the flow ends, and at least partially structured sheet metal layers having structures forming walls defining channels through which a fluid can flow in one flow direction. The channels have sizes or numbers varying in the different successive sections in the flow direction. At least a part of the structured sheet metal layers extend from the inlet flow end to the outlet flow end. Each of the sheet metal layers has at least a first structure and a second structure with different dimensions. At least one of the structures extends over only one of the sections. A method for manufacturing the honeycomb body is also provided.
