ABSTRACT:
A honeycomb segment3includes a plurality of cells5functioning as fluid passages and disposed in parallel with one another in the central axis direction. Cells at four corners of both end faces of the honeycomb segment3are plugged with a plugging material7. Since occurrence of chipping or a crack during handling before joining honeycomb segments can be reduced, productivity and yield of a honeycomb structure can be improved with the honeycomb segment.
