A honeycomb segment 3 includes a plurality of cells 5 functioning 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 segment 3 are plugged with a plugging material 7 . 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.
