    • PROBLEM TO BE SOLVED: To supply a slurry only to the end parts of a work without bonding the same to the side surfaces of the work. SOLUTION: The coating hopper is equipped with a liftable annular bag 2 made of a rubber for sealing the whole outer peripheral surface Ws of a honeycomb carrier W forming an almost cylindrical shape in an expanded state and a slurry metering container 3 positioned under the annular bag 2 to house the slurry supplied from the lower end Wb of the honeycomb carrier W. The annular bag 2 is provided with an air piping 4 for introducing air into the annular bag 2 to expand the annular bag 2 to bring the same into contact with the outer peripheral surface Ws of the honeycomb carrier W under pressure and an air discharge port 5 for discharging the compressed air to the slurry metering container 3 in a state approaching the slurry metering container 3. The slurry metering container 3 is provided with an air introducing tube 6 connected to the air discharge port 5 of the annular bag 2 to introduce the compressed air and a supply tank 7 for raising the liquid surface Sa of the slurry by the compressed air introduced through the air introducing tube 6 to supply the slurry S from the lower end Wb of the honeycomb carrier W.
