Abstract
A metal powder manufacturing device includes: an atomization tank; a crucible in which a molten metal is stored; a molten metal nozzle that allows the molten metal stored in the crucible to flow downward into the atomization tank; and a fluid spraying nozzle including a plurality of spraying holes that spray a fluid to an atomization tank side end part of the molten metal nozzle to pulverize a molten metal flow flowing downward from the molten metal nozzle. The molten metal nozzle includes a molten metal nozzle body and an orifice part having an inside diameter equal to or smaller than an inside diameter of the molten metal nozzle body, and a material of the orifice part is harder than a material of the molten metal nozzle body.
