A honeycomb filter (10) obtained by bonding a plurality of honeycomb segments (4, 5) each having a plurality of through-holes (21) which are separated from each other by porous partition walls (20) and which are plugged alternately at the exhaust gas inlet face (16) and exhaust gas outlet face (14) of honeycomb segment, wherein each two adjacent honeycomb segments (4, 5) are contacted with each other at each a portion of their sides (6, 7) facing each other and are bonded with each other at least at part of each portion of said sides (6, 7) other than the contacted portion (8, 9) via a bonding material having a strength lower than that of a basal body of honeycomb segment. With this honeycomb filter, the thermal stresses generated among the respective portions constituting the filter is reduced and the generation of cracks, etc. can be prevented considerably, and this honeycomb filter functions well particularly. This method is preferably applicable to a filter being composed mainly of silicon carbide or of metallic silicon and silicon carbide. <IMAGE> |
