Method of manufacturing fine metal powder and fine metal powder manufactured by using the same

Abstract

There are disclosed a method of manufacturing fine metal powder and fine metal powder manufactured by using the same. The method of manufacturing fine metal powder includes forming a pattern having a predetermined size and shape on a base substrate, forming a metal film on the pattern, and separating the metal film from the pattern to obtain individual metal particles having a predetermined size and shape. The fine metal powder manufactured by the method has a uniform shape and a uniform particle size distribution. The fine metal powder is in the form of flakes, having a large ratio of particle diameter to thickness.
