Abstract
The present invention provides a method for producing a porous copper foil. The method of the present invention includes the steps of forming an oxide film by providing a chromium-containing compound to a metal surface of a cathode; forming a copper foil on the oxide film by performing electrolysis of copper; and removing the copper foil from the metal surface of the cathode. The method of the present invention is simple and time-saving, and the porous copper foil of the present invention has reduced roughness difference between both sides of the porous copper foil.
