An extruded honeycomb body, in particular a catalytic converter carrier body, having a plurality of passages through which a fluid can flow and of which at least a portion is bordered and/or separated from each other with passage walls of a first thickness and at least a portion is bordered and/or separated from each other with passage walls of a second thickness. The first thickness is less than the second thickness and the honeycomb body has a wall structure which stabilizes it and which is formed with passage walls of the second thickness. The stabilizing wall structure has a plurality of approximately straight wall portions of the second thickness which, transversely with respect to the local configuration of the edge of the honeycomb body, extend from a respective outside into the interior of the honeycomb body or extend through the honeycomb body. Honeycomb bodies according to the invention, have good stability, and can have particularly thin passage walls whereby they have at least locally a particularly low thermal capacity.
