<p>A method of producing a honeycomb structure includes a first step that includes filling large pores formed in a primary fired body with a filling slurry that contains filling particles having an average particle size of 5 to 50 µm, the primary fired body including a partition wall that has a number of large pores having an average pore size of 100 to 300 µm, and firing the primary fired body to obtain a secondary fired body that includes a porous partition wall that has a number of pores having an average pore size smaller than that of the large pores, and a plurality of cells that are defined by the partition wall and extend between two end faces of the secondary fired body, and a second step that includes plugging the plurality of cells of the secondary fired body on either of the end faces or inside the plurality of cells to form plugging sections to obtain a honeycomb structure (100) that includes the partition wall (4) and the plugging sections (10), the partition wall (4) having a thickness of 76.2 to 177.8 µm, an average pore size of 8 to 30 µm, and a porosity of 10 to 35%.</p> |
