1. A honeycomb body for exhaust gas aftertreatment, comprising:
a plurality of interconnected metal foils having a respective diamond-shaped cutout, each of the interconnected metal foils being stacked on one another;
wherein the honeycomb body has a central first flow channel running in the axial direction of the honeycomb body, as an inflow section, and has a plurality of second flow channels between in each case two mutually adjacent metal foils;
wherein the first flow channel is in fluid communication with the second flow channels; and
wherein the second flow channels formed between two mutually adjacent metal foils run in a straight line and parallel to one another along a radial direction of the honeycomb body.
