Claim 8:
9. A crucible apparatus for a metal powder manufacturing device comprising:
a crucible in which a melting metal is stored; and
a molten metal nozzle that allows the melting metal stored in the crucible to flow downward into an atomization tank, wherein
a fluid is sprayed from a fluid spraying nozzle including a plurality of spraying holes provided in a periphery of the molten metal nozzle to an atomization tank-side end part of 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,
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.
