<p>A method of producing a honeycomb structure (20) comprising the steps of disposing an outer wall material (11) on the outer peripheral surface (3) of a cell structure (1) consisting of a plurality of cells (2) serving as fluid flow channels to produce an outer wall material disposition cell structure (10), and firing the outer wall material disposition cell structure (10), wherein an outer wall material disposition cell structure (10), in which the absolute value of the difference between the volumetric shrinkage percentage (firing shrinkage percentage) before and after the firing of the cell structure (1) and the firing shrinkage percentage of the outer wall material (11) is not more than 0.5%, is prepared and fired. A honeycomb structure producing method comprising the steps of disposing an outer wall material on an outer peripheral surface, and firing the structure, wherein the outer wall hardly cracks during firing, and a high-strength, large-sized honeycomb structure can be produced; and a high-strength, large-sized honeycomb structure whose outer wall hardly cracks.</p> |
