Abstract: PROBLEM TO BE SOLVED: To provide a collector allowing active material layers to be correctly stacked on and integrated with both its front and back surfaces, and of preventing the active material from falling off in manufacturing a secondary battery or in using it.
SOLUTION: In this collector A, front and back conductive resin layers 2 and 3 are stacked on and integrated with both front and back surfaces of metal foil 1; multiple through-holes A1 penetrating to the back surface of the metal foil 1 from the front surface of the resin layer 2 are formed; the active material layers can be stacked and integrated in separate processes on the one-side surface basis because the back-side openings of the through-holes A1 are closed by the resin layer 3; and thereby, the active material layers can simply and surely be stacked on and integrated with both the front and back surfaces of the collector by using a simple facility while correctly adjusting the thicknesses of the active material layers.

Abstract: PROBLEM TO BE SOLVED: To provide aluminum alloy foil which has excellent mechanical strength such as tensile strength and elongation, and formability, and has reduced pinholes as well.
SOLUTION: The aluminum alloy foil having excellent tensile strength and elongation and satisfactory formability, and having reduced pinholes as well comprises, by weight, 0.04 to 0.2% Si, 1.0 to 2.0% Fe, ≤0.01% Cu and ≤0.01% Mg, and the balance Al with inevitable impurities. The mean crystal grain size is 5 to 20 μm, and the mean grain size of subgrains is 0.5 to 3.0 μm. Further, the distributed density of Al-Fe compounds with a grain size of 0.1 to 2.0 μm is 3×10
5 to 20×10
5 pieces/mm
2 , and also, the dispersed density of Al-Fe compounds with a grain size of >2.0 μm is 1×10
4 to 10×10
4 pieces/mm
