The invention relates to a honeycomb arrangement, especially for a catalytic emission control system of an automobile. The arrangement comprises a honeycomb body (1) with a fluid inlet side (2) and a fluid outlet side (3), consisting of at least partially structured sheet layers that form channels through which a fluid can pass. These channels correspond to the way in which the sheets are layered or wound. The honeycomb body (1) is surrounded by an inner casing tube (4) and an outer casing tube (5) arranged concentrically in relation thereto. The inner casing tube (4) is configured as a corrugated hose in at least one axial sub-area (6). According to the invention, the inner casing tube has at least one other axial sub-area (7) which lies flat against the honeycomb body (1). The corrugated sub-area (6) and the outer casing tube (5) are interconnected by a partial, axial joint (8). The flat sub-area (7) and the honeycomb body (1) are interconnected at least by a partial, axial joint (8). The invention provides a technically reliable means of producing honeycomb arrangements which are able to withstand considerable stresses and which perform well in cold starts in the emission control system of an automobile (FIG.1 )
