Abstract
A layered solid-state battery that includes a first unit cell, a second unit cell, and an internal collection layer that is disposed to intervene between the unit cells. Each of the unit cells includes a positive electrode layer, a solid electrolyte layer, and a negative electrode layer that are sequentially stacked. The internal collection layer has one side surface that is in contact with the positive electrode layer of the first unit cell and the other side surface that is in contact with the negative electrode layer of the second unit cell. Also, the internal collection layer contains an electron conductive material and an ion-conductively insulating specific conductive material.
