Zusammenfassung:	In this method for producing a metal powder, in a sealed crucible disposed in a reaction vessel, at least a portion of a metal raw material introduced into the crucible is heated and melted, a molten metal is stored, at least a portion of the molten metal is evaporated, and a metal vapor is generated. The metal vapor is moved from the crucible to a cooling pipe together with a carrier gas introduced into the crucible to be cooled. In this method for producing a metal powder, a gas introduced into the reaction vessel from outside the reaction vessel absorbs heat from the crucible, thereby cooling the crucible and raising the temperature of the gas, and at least a portion of the gas after temperature raising is introduced into the crucible as the carrier gas. According to the present invention, it is possible to provide a method and a device for manufacturing a metal powder, which can solve the technical problems of deterioration of a crucible and contamination of impurities to the metal powder, and which can c
