<p>A honeycomb filter for clarifying an exhaust gas which is composed of a cylindrical article of a porous ceramic having a number of through holes so arranged as to be parallel with one another in the longitudinal direction thereof and as to be separated from one another by the wall portion thereof, wherein at one end of the cylindrical article, predetermined through holes are sealed by a filler, and at the other end thereof, the through holes not sealed at the above one end are sealed by a filler, and wherein a part or the whole of the wall portion functions as a filter for capturing particles, characterized in that a flexural strength Fα (MPa) of the honeycomb filter and a length L (mm) of the through holes in the longitudinal direction satisfies the relationship of Fα × L ≥ 30. The honeycomb filter for clarifying an exhaust gas is free from the occurrence of cracks or the loss of a filler during use and exhibits excellent durability.</p> |
