PURPOSE: To provide a method for preparing metal nanoparticles by electrolysis to prepare nanoparticles of metal environmentally friendly, effectively control size of metal particles and mass-produce metal powder of uniform particles by using electrodes, small quantity of additives and pure water without harmful metal salts and applying an external force to induce formation and dispersion of metal particles. CONSTITUTION: In a method for preparing metal into nanoparticles by electrolysis, the method is characterized in that two electrode rods(3) are disposed with being spaced apart from each other in a solution(2) prepared by dissolving any one of an environmentally friendly metal ion reducing agent and organic metal ion reducing agent into pure water, the electrode rods are formed of the same constituent as metal particles desired to be obtained so that the electrode rods are dissolved into the solution by electricity, and one or more selected from ultrasonic generator(4) and agitator(5) are arranged in the solution to disperse metal particles in the solution in a uniform particle shape.
