Abstract
A method of producing metal powder by reducing ions of a metal for precipitation by performance of a reducing agent in a liquid-phase reaction system, wherein the metal is precipitated as metal powder particles by being reduced under conditions in which the exchange-current density of an oxidation-reduction reaction between the metal ions and the reducing agent is 100 μA/cmor less, the exchange-current density being determined by the mixed potential theory.
