Abstract
A solid electrolyte battery h which includes a wound electrode incorporating a positive electrode with a two-sided elongated positive-electrode collector on which positive-electrode active material layers are formed, a two sided negative electrode with an elongated negative-electrode collector on which negative-electrode active material layers are formed and a solid electrolyte layer formed between the positive and the negative electrodes where, the total film thickness of the positive-electrode active material layers satisfies a range from 60 μm to 150 μm, and the ratio A/B of the total film thickness A of the positive electrode active material layers with respect to the total thickness B of the negative-electrode active material layers satisfies a range from 0.5 to 1.2.
