Abstract:
1. A honeycomb filter for trapping particulate matter contained in dust-containing fluid, the filter comprising: a number of through-holes surrounded by partition walls and extending in an axial direction, the partition walls having filterability, predetermined through-holes being plugged at one end, remaining through-holes being plugged at the other end, wherein in a section of the honeycomb filter perpendicular to the axial direction, heat capacity in a central part of the honeycomb filter is higher than that in a peripheral part of the honeycomb filter, wherein in the section of the honeycomb filter perpendicular to the axial direction, a thickness of the partition wall in the central part is set to be larger than that of the partition wall in the peripheral part.
