Disclosed is a method for producing a catalyst carrier element (1) comprising a honeycomb body (2) which is provided with a plurality of at least partly structured layers (3, 4) forming channels (5) that are penetrated by a fluid, a housing (6) which at least partly envelops the honeycomb body (2), and at least one corrugated sheath (7) which is arranged between the honeycomb body (2) and the housing (6) and connects the honeycomb body (2) to the housing (6). The inventive method comprises the following steps: - the honeycomb body (2) is produced, said honeycomb body (2) having an outer dimension (8) that is formed at least in part by ends (9) of the layers (3, 4); the at least one corrugated sheath (7) having a profile (10) is produced; - a housing (6) having an inner contour (11) is produced; - the honeycomb body (2) is inserted into the at least one corrugated sheath (7); - the at least one corrugated sheath (7) comprising the honeycomb body (2) is inserted into the housing (6); - the housing is calibrated (6), at least the inner contour (11) and preferably also the profile (10) of the at least one corrugated sheath (7) being reduced while the ends (9) snap into the structure of the corrugated sheath (7) and almost entirely rest against said corrugated sheath (7). At least 90 percent of the ends (9) of the catalyst carrier element which is produced according to the inventive method are connected to the at least one corrugated sheath (7) by means of a joining technique.
