<p>A honeycomb filter includes a pillar shape honeycomb structure that has a plurality of cells 28, which are arranged in a honeycomb shape and partitioned by cell walls 27, and a plug 30 that seals either one of open ends of each cell 28. In the honeycomb filter, the plug 30 has a clad 30a that occupies a peripheral region near the cell wall 27 and a core 30b that occupies a central region including the central axis of the cell 28. The Young's modulus of the clad 30a differs from the Young's modulus of the core 30b.</p> |
