A canning structure comprises a ceramic honeycomb structure before carrying a catalyst, fixed beforehand within a metal case by a holding material. An impermeable layer is provided on at least one edge plane in the longitudinal direction of the holding material. 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.

What is claimed is: 1. A canned ceramic honeycomb structure, comprising: a metal case; a ceramic honeycomb structure not loaded with a catalyst and contained within said metal case; a holding material located between said ceramic honeycomb structure and said metal case, said holding material and said metal case having a common longitudinal direction, wherein the holding material has at least one peripheral edge defining at least one edge plane perpendicular to said longitudinal direction; and a combustible impermeable layer, which is combustible at a temperature less than about 700° C., located on said at least one edge plane, said combustible impermeable layer being provided between said ceramic honeycomb structure and said metal case. 2. A canning structure according to claim 1, wherein the length of said combustible impermeable layer is not greater than 10 mm. 3. A canning structure according to claim 1, wherein plane pressure properties of said combustible impermeable layer are not greater than those of said holding material. 4. A canning structure according to claim 1, wherein said ceramic honeycomb structure has a second edge plane, and said at least one edge plane of said holding material having said combustible impermeable layer located thereon and said second edge plane of said ceramic honeycomb structure are substantially in common. 5. A canning structure according to claim 1, wherein said combustible impermeable layer comprises a combustible impermeable material adhered to said holding material along said at least one edge plane of the holding material. 6. A canning structure according to claim 1, wherein said combustible impermeable layer is a thin film. 7. A canning structure according to claim 1, wherein said combustible impermeable layer comprises a rope having one of a circular, quadrangular, or arbitrary cross-section. 8. A canning structure according to claim 1, wherein said combustible impermeable layer comprises resin selected from the group consisting of plastic, rubber, paper, cloth, and fiber. 9. A canning structure according to claim 1, wherein said combustible impermeable layer comprises a portion located adjacent said at least one edge plane of said holding material, said portion being impregnated with combustible impermeable matter selected from the group consisting of oils and fats. 10. A canning structure according to claim 1, wherein the partition thickness of said ceramic honeycomb structure is not greater than 0.10 mm. 11. A canning structure according to claim 1, wherein said holding material comprises a non-intumescent ceramic fiber mat. 12. A canning structure according to claim 1, wherein the combustible impermeable layer is combustible at a temperature less than about 500° C. 13. A canning structure according to claim 1, wherein the combustible impermeable layer is combustible at a temperature in a range of about 500° C. to about 700° C.
