HONEYCOMB FILTER

摘要

A honeycomb filter (100) has a plurality of flow paths (110) separated by partition walls (120); the plurality of flow paths (110) have a plurality of flow paths (110a) and a plurality of flow paths (110b); of the plurality of flow paths (110b), one flow path (110b) and another flow path (110b) are adjacent to each other; at one side of the honeycomb filter (100), the ends of flow paths (110a) are sealed; at the other side of the honeycomb filter (100), the ends of flowpaths (100b) 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.
