Abstract
A method for producing a highly reliable ceramic honeycomb structural body having selectively, tightly sealed open end surfaces, including steps of attaching a film or mask on an open end surface of a ceramic honeycomb structural body, introducing a ceramic sealing material, preferably having a viscosity of 50-1,500 poises, into throughholes of said honeycomb body through apertures bored at selected positions of the film or mask, rapidly drying to solidify the sealing material followed by sintering. The drying step takes place 2 minutes after the introduction of the sealing material into the throughholes and is performed, preferably with hot air at 100.degree.-300.degree. C.
