Abstract

A method for producing a ceramic honeycomb filter having a ceramic honeycomb structure having plugs in predetermined cells: comprising using an apparatus having a reservoir having an inlet for a plugging material slurry and an upper opening, a porous plate with pluralities of openings covering the upper opening of the reservoir, and a holding member fixed to an upper end of the reservoir; keeping a lower surface of the sealing film attached to a lower end surface of the ceramic honeycomb structure apart from an upper surface of the porous plate by a distance D of more than 0 mm and 2.0 mm or less; supplying a predetermined volume of the plugging material slurry into the reservoir to introduce it into the predetermined cells of the ceramic honeycomb structure; rotating the ceramic honeycomb structure after sealing of the ceramic honeycomb structure is released; and lifting the ceramic honeycomb structure after the rotation starts.
