METHOD FOR MANUFACTURING A CERAMIC HONEYCOMB STRUCTURE
A ceramic honeycomb structure having a large number of flow paths partitioned by porous cell walls, the cell walls having porosity of 40-60%; pores opening on the cell wall surface having an opening area ratio (the total opening area of pores opening on the cell wall surface per a unit area) of 15% or more; the median opening diameter of the opening pores being 10 µm or more and less than 40 µm on an area basis, when the opening diameter of each pore opening on the cell wall surface is expressed by an equivalent circle diameter (a diameter of a circle having the same area as the opening area of each pore); the density of pores having equivalent circle diameters of 10 µm or more and less than 40 µm being 350/mm 2 or more; and the average circularity of pores having equivalent circle diameters of 10 µm or more and less than 40 µm being 1-2.
