ABSTRACT:
Cordierite honeycomb structural bodies having excellent coatability for a material of high specific surface area and a catalyst thereon and low thermal expansion are disclosed. The cordierite honeycomb structural body as a chemical composition essentially consisting of from 42 to 56% of SiO.sub.2, from 30 to 45% of Al.sub.2 O.sub.3, and from 12 to 16% of MgO in terms of weight and contains cordierite as a main component of a crystalline phase. Porosity of the cordierite honeycomb structural body is from over 30% to not more than 42%. The total volume of pores having a diameter of from 0.5 to 5 .mu.m and the total volume of pores having a diameter of not less than 10 .mu.m are not less than 70% and not more than 10% of the total pore volume of the honeycomb structural body, respectively.
