<p>A method for producing a ceramic honeycomb structure having a large number of paths partitioned by porous cell walls, the cell walls having thickness of 0.17-0.45 mm and porosity of 40% or more, comprising the steps of preparing a moldable material comprising a ceramic material powder, a binder, a pore-forming material and water, extruding the moldable material to form a honeycomb-shaped green body, and drying and sintering the green body, the pore-forming material having a melting point of 40-110°C, being solid in the moldable material, and being melted in the drying step so that 25% or more thereof is removed from the green body in the drying step.</p> |
