PROBLEM TO BE SOLVED: To provide a device for manufacturing high-quality coated fuel particles by making it possible to manage the gasification and supply of liquid materials in a process for manufacturing coated fuel particles for a high-temperature gas-cooled reactor more stably than ever. SOLUTION: The device for manufacturing coated fuel particles for a high-temperature gas-cooled reactor has a means for gasifying and supplying the liquid materials and a pipe for feeding a fluidized gas and a coating material gas to a gas spouting nozzle in a bottom part of a reaction container, and the gas supply means includes a liquid feeding mechanism for introducing the liquid materials from a material tank to the pipe and a vaporization mechanism for heating and vaporizing the liquid materials introduced into the pipe and merging into the fluidized gas in the pipe in a predetermined position upstream of the nozzle to pass the liquid materials as a steam-mixed gas toward the side of the reaction container.
