A method for producing a metal powder which comprises effecting a plasma discharge in water between an electrode of an elemental metal and a counter electrode to generate a metal ion vapor and contacting the metal ion vapor with water to thereby convert the metal ion vapor to a powder; and an apparatus for producing a metal powder which comprises a power source for high voltage high current discharge, a device for supplying an electrode of a metal such as titanium, a high voltage discharge device having an electrode of a metal such as titanium and a counter electrode, a device for vibrating or sliding anelectrode, a water tank, a water inlet, an outlet and a discharge pump for discharging a dispersion of a metal such as titanium, and a device for separating and recovering a powder of a metal such as titanium. The method and the apparatus allows the production of a metal powder having high purity and being uniform in the shape and size of particles, at a low cost.
