PROBLEM TO BE SOLVED: To prevent the occurrence of a sink in the sealing parts of the cells of a honeycomb structure. SOLUTION: In manufacturing the honeycomb structure, pressure is applied to the bottom surface of a storage container in such a state that the end surface of the honeycomb structure having a large number of axially piercing cells partitioned by partition walls is immersed in the slurry containing a ceramic powder in the storage container to introduce the slurry into at least a part of the cells under pressure and the honeycomb structure is separated from the storage container to seal at least a part of the cells. When the honeycomb structure is separated from the storage container, the slurry bonded to the end surface of the honeycomb structure is removed. Alternatively, air is blown against or heating is applied to the end surface part of the honeycomb structure separated from the storage container to dry the slurry. COPYRIGHT: (C)2005,JPO&NCIPI |
