Abstract
A method for producing a ceramic honeycomb filter having large numbers of flow paths partitioned by cell walls, the flow paths having plugs at positions separate from an end surface of the honeycomb filter, comprising the steps of introducing a base-forming material into the flow paths on one end surface side, charging a plug-forming material into flow paths to be provided with plugs from the other end surface side, and sintering it.
