Summary:A paste-like active material mixture prepared by mixing an active material powder and a particulate material comprising a polymer soluble in a nonaqueous electrolytic solution is applied to, e.g. collectors 1 c and 2 c to a uniform thickness, and then dried to form positive and negative electrodes 1, 2 containing an active material powder and a particulate polymer. The two electrodes are assembled into an electrode laminate into which the foregoing electrolytic solution is then injected.
