The current collector plate arrangement structure of the bipolar solid-state battery includes a battery cell stack formed by stacking a plurality of solid-state battery cells each including a positive electrode active material layer, a negative electrode active material layer, and a solid electrolyte layer disposed between the positive electrode active material layer and the negative electrode active material layer and in contact with the positive electrode active material layer and the negative electrode active material layer. The bipolar solid-state battery includes a positive electrode current collector and a negative electrode current collector on a side surface with respect to a stacking direction. Current collector plates and of the solid-state battery cells are arranged on at least one of a front surface serving as one end surface in the stacking direction and a rear surface serving as the other end surface in the stacking direction.
