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; the cross section of flow paths (110b) have 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 thickness of the partition walls (120b) that separate adjacent flow paths (110b) is greater than the thickness of the partition walls (120a) that separate flow paths (110a) and flow paths (110b).
