A metal powder production apparatus includes a supply part for supplying molten metal and a nozzle provided below the supply part. The nozzle is provided with a flow path through which the molten metal supplied from the supply part can pass, the flow path having a gradually reducing inner diameter portion whose inner diameter is gradually reduced in a downward direction. The nozzle is further provided with an orifice opened at a bottom end of the flow path and adapted to inject fluid toward the flow path. The nozzle has a first member and a second member provided below the first member with a space left between the first member and the second member, wherein the orifice is defined by the first member and the second member. A clamp for restraining the orifice from being enlarged by the pressure of the fluid passing through the orifice is provided on the nozzle.
