Abstract
This invention discloses ceramic honeycomb structural bodies having high thermal shock resistance and mechanical strength in which partition walls forming numerous parallel channels of the honeycomb structural bodies and/or connecting portions of the partition walls are constructed so as to have flexibility. The flexibility allows thermal stress generated in the honeycomb structural bodies to be absorbed. The bodies are characterized in that a given area of outer circumferential annular portion of said ceramic honeycomb structural bodies has a structure having a higher rigidity than the inner portion.
