摘要： An object of the present invention is to provide an electrolytic aluminum foil having no significant difference in properties between one surface and the other surface thereof, and also a method for producing the same. Another object is to provide a current collector for an electrical storage device using the electrolytic aluminum foil, an electrode for an electrical storage device, and an electrical storage device. An electrolytic aluminum foil of the present invention as a means for achieving the object is characterized in that both surfaces of the foil have L* values of 86.00 or more in the L*a*b* color space (SCI method). The electrolytic aluminum foil of the present invention can be produced, for example, employing a method for producing an electrolytic aluminum foil, which comprises applying a current between a cathode drum partially immersed in a plating solution and an anode plate immersed in the plating solution to form an aluminum film on the surface of the cathode drum, and then separating, from the cathode drum, the aluminum film raised from the liquid surface by rotating the cathode drum, and in which the dew point of a treatment atmosphere at the time of the separation of the aluminum film from the cathode drum to give an electrolytic aluminum foil is controlled to be −50.0° C. or less.
