<p>A honeycomb segment 2 has two kinds of cells 5a and 5b having different cross-sectional areas in a cross-section cut along a plane perpendicular to the longitudinal direction of the segment. When the cells are cut along a plane perpendicular to the longitudinal direction of the cells, each cross-sectional area of first cells (large cells) 5a is larger than that of second cells (small cells) 5b. The first cells 5a are formed into an octagon where corners are cut off or into a square having circular arc corners. The second cells 5b are formed into a square. The thickness of a 1-1 wall between the adjacent first cells 5a is larger than that of a 1-2 wall between each first cell 5a and each second cell 5b adjacent to the first cell 5a. A honeycomb filter of the present invention can improve a fluid flow among partition walls to heighten a particulate collecting performance, and can increase the strength of the filter.</p> |
