A ceramic honeycomb structure comprising porous cell walls defining large numbers of flow paths, the cell walls having (a) porosity of 55% or more and less than 65%, and (b) 35,000/mm3 or more of substrate branches, wherein the number of substrate branches is defined by the number of branch points (including connecting points of 3 or more branches and connecting points of different-width branches) per a unit volume, in a network structure obtained by the skeletonization of the three-dimensional structure of cell wall substrates determined by X-ray CT.
