Provided is a method for producing a superfine metal powder, which can use a wide variety of raw materials, can control the particle diameter of the resultant metal powder as desired, and further canbe practiced at a low cost and is excellent in safety. A method for producing a superfine metal powder which uses a burner and a furnace capable of forming a high temperature reducing atmosphere and an apparatus for separating a gas and a powder generating from the furnace and recovering the powder, wherein the burner has a function to blow a powdery metal compound as a raw material into a high temperature reducing flame, and a raw material powder is heated efficiently in the stream of a high temperature reducing flame and is reduced at a high rate into a superfine metal powder, and wherein the particle diameter of the superfine metal powder can be controlled by the control of an oxygen ratio (the ratio of the amount of a combustion-supporting gas to be supplied to the burner to that of the combustion-supporting gas required for the perfect combustion).
