    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 first unit cell and the second unit cell. Each of the unit cells is constituted of a positive electrode layer, a solid electrolyte layer, and a negative electrode layer that are sequentially stacked. The internal collection layer is disposed to be in contact with each of the negative electrode layers of the unit cells. Also, the internal collection layer contains an electron conductive material and an ion-conductively electrically conductive specific conductive material.
