PURPOSE: A metallic collector body, a manufacturing method thereof, and an electrochemical capacitor including the same are provided to improve electric resistance and bond strength by forming a groove at the surface of a metal substrate and forming a carbon buffering layer and a conductive layer at the metal substrate. CONSTITUTION: A groove(11) is formed on the surface of a metal substrate(10). The groove is formed by etching and partially corroding the surface of the metal substrate. The groove formed on the metal substrate has the depth of 1.0μm-5.0μm. A native oxide film formed on the metal substrate is removed. A carbon buffering layer(20) is formed at the metal substrate from which the native oxide film is removed. The carbon buffering layer is formed at a part or entire region of a concavo-convex area which is positioned between grooves formed on the metal substrate. A conductive layer(30) is formed on the carbon buffering layer.
