ABSTRACT:
A honeycomb structural body is constituted with a ceramic block comprising a plurality of through-holes arranged in a longitudinal direction and separated from each other through partition walls, either end portions of which through-holes being sealed. The ceramic block constituting the honeycomb structural body is made of a composite material consisting of ceramic particles and crystalline silicon and having an excellent thermal conductivity, so that the honeycomb structural body is excellent in the thermal diffusibility but also excellent in the resistance to thermal shock because the storing of thermal stress is less and no crack is caused even if a temperature distribution is caused at a relatively low temperature or cool-heat cycle is repeated over a long period of time.
