ABSTRACT:
A honeycomb filter includes a honeycomb fired body having cells longitudinally disposed either end of each cell being sealed. The honeycomb filter includes an outlet-side catalyst supporting area, an inlet-side catalyst supporting area, and a catalyst unsupporting area formed between the catalyst supporting areas. A thermal conductivity of the catalyst unsupporting area is larger than those of the catalyst supporting areas. Y (%), Z (%), and X (%) satisfy the following inequalities, about 1≦Y≦about 19, (880−70Y)/9≦Z≦(825−15Y)/9 (about 1≦Y≦about 10), (330−15Y)/9≦Z≦(1375−70Y)/9 (about 10≦Y≦about 19), and X=100−Y−Z in which Y, Z, X indicate a ratio of a length of the outlet-side catalyst supporting area, the inlet-side catalyst supporting area, the catalyst unsupporting area, respectively, to an entire length of the honeycomb filter.
