ABSTRACT:
In order to obtain a honeycomb structural body having excellent mechanical strength, which can eliminate a waste use of a catalyst, incomplete cells at an outermost peripheral portion of the honeycomb structural body are sealed selectively by ceramic materials. An incomplete cell does not have a square cross section if the complete cell has a square cross section, and is preferably defined by the cell having an area not more than 90% as that of the complete cell.
