To obtain a method for producing a honeycomb structure which has little generation of deformation and cracking after the drying or burning of the honey comb molded body even if a pore forming agent is largely added thereto for the purpose of increasing its porosity.

A raw material to become into a cordierite composition, a molding aid, a pore forming agent and water are mixed and kneaded. A honeycomb body is produced by an extrusion molding method therefrom, and, after that, the molded body is dried and burnt to produce the porous ceramic honeycomb structure. The production method contains (a) a first drying stage where 60 to 90 mass% of water contained in the molded body is evaporated by microwaves or dielectric drying, and (b) a second drying stage where the remaining of the water contained in the molded body is evaporated by hot-air drying, or further, (c) a first burning stage where the pore forming agent is burnt away by 50 to 70 mass% by a hot-air circulation furnace, and (d) a second burning stage where the remaining of the pore forming agent is burnt away by a single furnace, a tunnel furnace or the like.
