<p>It is to propose a ceramic honeycomb structural body capable of realizing not only collection and removal of particulates included in an exhaust gas discharged from an internal combustion engine but also conversion of harmful gases. This honeycomb structural body comprises a sintered body having a pore structure wherein pores having a pore size ranging from 1.0 to 150 µm are a first pore group and pores having a pore size ranging from 0.006 µm to less than 1.0 µm are a second pore group in a pore size distribution curve, one peak in the pore size distribution is existent in the first pore group region and plural peaks in the pore size distribution are existent in the second pore group region.</p> |
