ABSTRACT:
There is disclosed a honeycomb structure1having a plurality of cells4partitioned by cell walls2to function as fluid passages, a predetermined cell4being plugged by a plugging material at one end face, a remaining cell4being plugged by the plugging material at the other end face, wherein a Young's modulus of the plugging material is lower than that of the cell wall2. A strength of the plugging material is lower than that of the cell wall. A porosity of the plugging material is 97% or more of that of the cell wall. There is provided a honeycomb structure whose end face is not easily cracked and which is superior in durability.
