Summary:The present invention relates to the electrode of an EDLC which can easily increase the surface area of a current collector by manufacturing the current collector using a foamed metal as a support, and can increase the electrode energy of the EDLC by easily increasing the surface area of the electrode when the current collector using the foamed metal is applied to an electrode. The electrode includes a current collector; and an electrode material layer formed by applying an electrode material to one surface or the other surface of the current collector. The current collector includes a foamed metal, and a metal layer on the front surface of the foamed metal. The electrode material layer is formed by applying the electrode material on the surface of the metal layer to be located on one surface or the other surface of the foamed metal. 본 발명은 발포 금속을 지지체로 하여 집전체를 제조함으로써 집전체의 표면적을 용이하게 증가시킬 수 있으며, 발포 금속을 이용한 집전체를 전극에 적용 시 전극의 표면적을 용이하게 증가시킬 수 있어 EDLC의 에너지 밀도를 개선시킬 수 있는 EDLC의 전극에 관한 것으로, 집전체; 및 집전체의 일면이나 타면에 전극물질을 도포하여 형성되는 전극물질층을 포함하고, 집전체는 발포 금속과, 발포 금속의 전면에 형성되는 금속층을 구비하며, 전극물질층은 발포 금속의 일면이나 타면에 위치되도록 금속층의 표면에 전극물질을 도포하여 형성되는 것을 특징으로 한다.
