<p>A high flexuous copper foil and a method for producing the same are provided to implement the optimum folding endurance by controlling factors of sulfur content, gravimetric anomaly, crystal orientation, crystal particle size. A high flexuous copper foil comprises followings. A surface roughness of a glossy surface and a roughened structure is the respective 1.0 ~ 3.5mum. The sulfur content is less than 0.1% and the carbon content is less than 0.05%. The crystal orientation is 30% or greater. The crystal particle size after heat treatment is 1mum or greater. The gravimetric anomaly is 2g/m^2 or less. An electrolyte is continuously supplied to a container. The container has a drum(20) and an anode(30).</p> |
