PROBLEM TO BE SOLVED: To provide a method for manufacturing a heat-receiving device of a nuclear fusion apparatus, which has improved quality and reliability of heat-receiving plate. SOLUTION: The method for manufacturing the heat-receiving device comprises preparing a pool type structure made of a thermal spray material having a channel, thermally spraying a mixture of a material of the heat-receiving plate 11, tungsten for instance, and a material of a heat sink, copper for instance, and forming a content- inclined sprayed film 20 to form the heat-receiving plate 11. Then, the method forms a content-inclined sprayed film 20, without making a free margin exist on an interface between the content-inclined sprayed film 20 of the heat-receiving plate 11 and the thermal spray material of a heat sink 12, and improves quality and reliability of the heat-receiving plate 11, because peeling and cracking are inhibited from occurring on the interfaces in the content-inclined sprayed film 20, of which the material mixed ratios vary. In addition, the method contributes to thickening of the content-inclined sprayed film 20 to be formed into several millimeters or thicker, and reduction of the manufacturing cost for the heat-receiving device 10 of the nuclear fusion apparatus, because the content-inclined sprayed film 20 can be stably formed over a wide area.
