ABSTRACT:
A cell structure10having a plurality of cells2which are partitioned with partition walls1to form a honeycomb and which are flow paths of fluid, an outer wall5which encloses the cells2and a cavity3which pierces in the direction of a central axis P of the structure through a portion including the central axis P or a given axis parallel to the central axis P, where the cell structure further has an inner wall4on the inner surface of the cavity3, a method for producing the cell structure, and a catalyst structure. The cell structure having the cavity has an excellent isostatic breaking strength and can exhibit proper sealing function in its cavities. Furthermore, a method for producing the cell structure, the catalyst structure, etc. are provided.
