A canning structure comprises a ceramic honeycomb structure; said honeycomb structure having been not loaded with a catalyst, a metal case and a holding material, and said ceramic honeycomb structure being canned in said metal case and being held by said holding material thereto. An impermeable film is provided between the ceramic honeycomb structure and the holding material. The canning structure has an impermeable film provided between the ceramic honeycomb structure and the holding material, and then a catalyst slurry is poured in only on the ceramic honeycomb structure side of the impermeable film, thereby preventing the holding material from carrying the catalyst, such that only the ceramic honeycomb structure carries the catalyst. Thus, the holding material does not carry expensive catalyst at the time of carrying catalyst, and accordingly chipping and cracking of the ceramic honeycomb structure can be prevented at the time of transporting, the catalyst carrying process, the canning process, and handling in each of the processes.
