<p>There is disclosed a honeycomb filter which can suppress generation of cracks in plugged portions due to heat generated by burning of a PM during regeneration. The honeycomb filter comprises a honeycomb basal body 2 including porous partition walls 6 arranged to form a plurality of cells disposed in parallel with one another and including inflow cells 4a into which a fluid can flow and outflow cells which are formed adjacent to the inflow cells 4a and out of which the fluid can flow; first plugged portions with which one end 5b of each of the inflow cells 4a is plugged; second plugged portions 3b with which the other end 5a of each of the outflow cells is plugged; porous collecting layers formed on the surfaces of the partition walls 6 on the side of the inflow cells 4a; and end aggregate layers made of a particulate aggregate material and formed on the surfaces of the first plugged portions on the side of the inflow cells, and a thickness of the end aggregate layers is from 0.5 to 5 mm.</p> |
