Abstract

A hhoneycomb body with thermal insulation, preferably for an exhaust gas catalytic converter, includes a plurality of honeycombs and thermal insulation having a plurality of stacked and/or wound insulating sheet layers which are mutually supported by microstructures provided in the insulating sheet layers so that intermediate spaces exist between the insulating sheet layers. The microstructures have a height of from 10 .mu.m to 250 .mu.m. The honeycomb body therefore has only slight heat losses to the environment.
