Abstract

An aluminum alloy foil for a current collector of an electrode is provided which has not only high electric conductivity but also high strength before and after a drying step, and is low in manufacturing cost. Provided is an aluminum alloy foil for a current collector of an electrode, containing 1.0 to 2.0 mass % (hereafter, simply referred to as '%') of Fe, 0.01 to 0.2% of Si, 0.0001 to 0.2% of Cu, and 0.005 to 0.3% of Ti, the remainder being Al and inevitable impurities, wherein an amount of Fe contained as a solid solution is 300 ppm or more, and particles of intermetallic compounds having an equivalent circle diameter of 0.1 to 1.0 μm exist at 1.0×10particles/mmor more.
