Claim 0:
1. A metal powder manufacturing device comprising:
an atomization tank;
a crucible in which a melting metal is stored;
a molten metal nozzle that allows the melting 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 the melting metal flowing downward from the molten metal nozzle, wherein
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,
a material of the orifice part is harder than a material of the molten metal nozzle body, and
an atomization tank-side end part of the orifice part, in an axial direction, is located above an atomization tank-side end part of the molten metal nozzle body, in the axial direction.
