摘要： A rolled foil of surface roughened copper as thick as 26 μm for example having a surface formed into an irregular shape with copper precipitated thereon by an electrolytic method is prepared as a negative electrode collector. Tin (Sn) or germanium (Ge) is deposited on the rolled foil described above, so that a negative electrode active material layer is formed. Note that the deposited tin or germanium is amorphous. The arithmetic mean roughness Ra in the surface-roughened rolled foil described above is preferably not less than 0.1 μm nor more than 10 μm. A non-aqueous electrolyte is produced by adding sodium hexafluorophosphate as an electrolyte salt in a concentration of 1 mol/l to a non-aqueous solvent produced by mixing ethylene carbonate and diethyl carbonate in the ratio of 50:50 by volume.
