PROBLEM TO BE SOLVED: To obtain manufacturing equipment of coated fuel particles for a high-temperature gas-cooled reactor proper for continuous production in which the in-core distribution of coating temperature giving a large effect on the characteristics of the coated layer does not vary in spite of repeated manufacturing. SOLUTION: In the manufacturing equipment of the coated fuel particle for the high-temperature gas-cooled reactor which is provided with a fluidized bed reacting device for laying the 4 coated layers on the surface of fuel kernel sintering uranium-dioxide, a seep gas supply pipe for supplying sweep gas other than coating gas and fluidized gas is provided outside the reaction pipe in the fluidized bed for exhausting the coating gas and/or fluidized gas having leaked out of the reaction pipe of the fluidized bed reacting device outside the device.
