Abstract
A porous honeycomb structure including cordierite, having a plurality of cell channels which pass through an interior of the porous honeycomb structure and are partitioned by porous partition walls, wherein the porous partition walls have a porosity of 45 to 60% as measured by a mercury intrusion method, wherein in a volume-based cumulative pore diameter distribution measured by the mercury intrusion method, the porous partition walls have a cumulative 10% pore diameter (D10) and a cumulative 50% pore diameter (D50) calculated from a small pore side, and satisfy a relationship of 0.45≤(D50−D10)/D50, and 3 μm≤D50≤10 μm.
