PROBLEM TO BE SOLVED: To obtain a manufacture equipment of clad fuel particle for a high-temperature gas reactor which can stabilize a temperature distribution in the core affecting the characteristics of cladding layer without variation and is proper for continuous production. SOLUTION: The manufacture equipment of clad fuel particle for a high-temperature gas reactor provided with a fluidized bed reacting device lays clad layers of the first clad layer having functions as a gas storage of gaseous fission products on the surface of the fuel kernel sintered with uranium dioxide and a buffer absorbing swelling of fuel kernel, the second clad layer having the retention function of gaseous fission products, the third clad layer having functions of the retention of solid fission products and a main strengthening member of the clad layer, and the fourth clad layer having functions of retention of gaseous fission products and a protection layer of the third clad layer. A space where a gas introduction means for a reaction tube of a fluidized bed of clad gas and/or fluidity gas exist and a space where a heater and an insulator exist are isolated from each other in the fluidized bed reacting device body.
