A solid electrolyte battery is disclosed incorporating a wound electrode having
a positive electrode with a collector having two sides on which positive-electrode
active material layers are formed, a negative electrode with a collector having
two sides on which negative-electrode active material layers are formed, and a
solid electrolyte layer formed between the positive electrode and the negative
electrode, wherein a total film thickness A of the positive-electrode active material
layers satisfies a range from 60 mm to 150 mm, and a ratio A/B of the total film
thickness A of the positive-electrode active material layers with respect to a
total thickness B of the negative-electrode active material layers satisfies a
range from 0.5 to 1.2.
