PROBLEM TO BE SOLVED: To provide a honeycomb structured body which is sufficiently porous with high specific surface area, preferably useable for automobile exhausting gas purifying filter even under high SV condition, containing fire resistant powder such as silicon carbide but can be economically manufactured with relatively low firing temperature, and the thermal conductivity of which is set at a proper value, by processing of plugging or catalyst supporting, etc. SOLUTION: The porous honeycomb structured body is composed of a lot of axial through holes surrounded by partitions containing aggregates of fire resistant powder 11, and metallic silicon 10. |
