    摘要： A ceramic honeycomb structure having pluralities of flow paths partitioned by porous cell walls, (a) the cell walls having porosity of 50-63%; and (b) in a pore diameter distribution in the cell walls measured by mercury porosimetry, (i) a pore diameter at a cumulative pore volume corresponding to 2% of the total pore volume being more than 180 µm and 250 µm or less, a pore diameter at 5% being 55-150 µm, a pore diameter d10 at 10% being 17-40 µm, a pore diameter d50 at 50% being 10-20 µm, a pore diameter at 85% being 5.5-10 µm, a pore diameter d90 at 90% being 3.5-9 µm, a pore diameter d98 at 98% being 2.5 µm or less, (d10 - d90)/d50 being 1.3-2, (d50 - d90)/d50 being 0.45-0.75, and (d10 - d50)/d50 being 0.75-1.4; (ii) the difference between a logarithm of the pore diameter at a cumulative pore volume corresponding to 20% of the total pore volume and a logarithm of the pore diameter at 80% being 0.39 or less; and (iii) the volume of pores of more than 100 µm being 0.03 cm 3 /g or less.
