Abstract:
Provided is a method for efficiently manufacturing fine metal particles applicable as a fuel cell electrode catalyst. Provided is a method of manufacturing fine metal particles, including the step of: a hydrogen bubbling step to perform bubbling to a reaction solution, wherein: the reaction solution is prepared by allowing seeds of fine metal particles in a dispersed state and a water soluble noble metal precursor to co-exist in a water-containing solvent; and the bubbling is performed with a reaction gas containing a hydrogen gas, is provided.
