CERAMIC HONEYCOMB FILTER AND PROCESS FOR PRODUCING THE SAME

A ceramic honeycomb filter comprising a honeycomb structure having large numbers of flow paths partitioned by porous cell walls, and plugs alternately formed in the flow paths on the exhaust-gas-inlet or outlet side, the outlet-side plugs having porosity of 65% or less, and the upstream-side end sur...
