| Summary: | In a method for producing a honeycomb structure which comprises disposing a material for forming outer wall on the outer peripheral surface of a cell structure having a plurality of cells serving as fluid flowing channels to produce a cell structure being provided with a material for forming outer wall and firing the resulting cell structure being provided with a material for forming outer wall , wherein a cell structure being provided with a material for forming outer wall in which the absolute value of the difference between the volumetric shrinkage percentage (firing shrinkage percentage) before and after firing of the cell structure and the firing shrinkage percentage of the material for forming outer wall is not more than 0.5% is produced and fired. There is provided a method for producing a honeycomb structure which comprises providing an outer wall on the outer peripheral surface and firing it, according to which the outer wall hardly cracks during firing and high-strength and large-sized honeycomb structure can be produced, and further provided is a high-strength and large-sized honeycomb structure in which the outer wall hardly cracks during firing. |
