Abstract: The present invention is a solid-state battery formed of a plurality of repeatedly stacked solid-state battery cells each including a positive electrode layer, a negative electrode layer, a solid-state electrolyte layer, and a pair of current collector layers sandwiching said layers. One surface of each of the current collector layers is in contact with the positive electrode layer or the negative electrode layer. The other surface of the current collector layer is in contact with the current collector layer of the neighboring solid-state battery cell. The coefficient of friction on the other surface of the current collector layer is higher than the coefficient of friction on the one surface of the current collector layer. This can provide a solid-state battery that does not suffer displacement or rotation when stacking.
