| 内容： | A method of manufacturing a ceramic honeycomb filter, comprising a ceramic honeycomb structure having a large number of flow passages partitioned by partition walls and seal parts. (a) A tubular member is inserted into each of one or more of flow passages opened at the end face of the ceramic honeycomb structure, and a seal material for forming the seal parts is filled from the tubular member into each of these flow passages. (b) The tubular members are moved to each of one or more flow passages to be sealed at positions in the diagonal direction of the flow passage and inserted therein, and the seal material is filled therein. Then, the steps above are repeated. |
