Zusammenfassung:	The present disclosure relates to a separator for a fuel cell and a manufacturing method of the same. The manufacturing method of the separator for a fuel cell includes: an unevenness forming step of forming a fine-sized unevenness on a surface of a metal base material; and a coating layer forming step of forming a coating layer by coating carbon on the surface of the metal base material on which the unevenness is formed. Through the manufacturing method, it is possible to obtain an effect of improving water discharge performance and adhesion between the metal base material and the coating layer by forming unevenness on a surface of a metal base material, and then forming a coating layer.
