<P>PROBLEM TO BE SOLVED: To provide a honeycomb filter by which thermal stress caused by combustion regeneration can be reduced. <P>SOLUTION: The honeycomb filter 100 has a plurality of flow paths 110 separated by partition walls 120; the flow paths 110 have a plurality of flow paths 110a and a plurality of flow paths 110b; of the flow paths 110b, one flow path 110b and another flow path 110b are adjacent to each other; end parts at one end side of the honeycomb filter 100 in the ends of flow paths 110a are sealed; end parts at the other end side of the honeycomb filter 100 in the ends of flow paths 110b are sealed; the cross section of flow paths 110b has long sides 150a and short sides 150b; each of the sides 140 of flow paths 110a faces a long side 150a of a flow path 110b; each of the short sides 150b of flow paths 110b faces a short side 150b of an adjacent flow path 110b; and the length of each of the short sides 150b is at least 0.3 mm. <P>COPYRIGHT: (C)2013,JPO&INPIT |
