PURPOSE: A manufacturing method of a fine metal particle is provided to maximize the efficiency when mixing with other materials or singly using for the purposes of antibiotic, sterilizing, polishing, preventing electrification, catalytic, blocking an electronic wave, electric/electronic material and sensitizing and to prevent the performance from decreasing since the metal particle is changed to an oxidized substance by contacting with water. CONSTITUTION: A manufacturing method of a fine metal particle is comprised of the steps of: manufacturing a solution 1 by adding a metal ion reducer such as an organic material included with Hydrazine, LiAIBH4, NaBH4 and ethylene oxide group; manufacturing a solution 2 by dissolving an aqueous salt capable of bringing out the metal particle ion to manufacture; and converting the metal ion to a metal atom by reducing if slowly adding up the solution 1 in the solution 2 while agitating; adding up a proper amount of a surface active agent in a solution formed with a particle.
