Abstract
A process for sealing an end face of a ceramic honeycomb structure includes introducing an expansive material which can be burned off, into through-holes not to be sealed, among through-holes of the honeycomb structure, expanding the expansive material to temporarily seal the through-holes not to be sealed, at their ends, filling a sealant into ends of through-holes to be sealed, and burning off the expansive material and sintering the sealant at the same time.
