| 发明名称 | Honeycomb structural body | ||
| 摘要 | A honeycomb structural body includes porous partition walls arranged to form a plurality of cells which become through channels of a fluid, porosities of the partition walls are from 45 to 70%, a pore diameter distribution of the partition walls is measured by mercury porosimetry, the pore diameter distribution indicates a bimodal distribution, in the bimodal distribution, a pore diameter at the maximum peak value of a small pore side distribution is from 1 to 10 μm, and a pore diameter at the maximum peak value of a large pore side distribution exceeds 10 μm, and a ratio between a pore volume of the small pores and a pore volume of the large pores is in a range of 1:7 to 1:1 in the honeycomb structural body. | ||
