Abstract
Cordierite honeycomb structural bodies having coefficients of thermal expansion of not more than 1.0x10.sup.-6, an improved thermal shock resistance, a very small leakage amount and an improved heat exchanging efficiency are provided by using very fine particles of kaolin and talc to restrict a total pore volume of a given pore diameter to a given range. The cordierite honeycomb structural bodies are useful in broader fields than conventional ones.
