To provide a solid-state battery in which the capacity and voltage can be optionally adjusted in a single battery and the installation space for the battery can be reduced.
A solid-state battery includes a plurality of electrode layers, and a solid electrolyte layer disposed between the electrode layers. The electrode layers includes positive electrode portion formed by filling a current collector including a metal porous body with a positive electrode material mixture, negative electrode portion formed by filling a current collector including a metal porous body with a negative electrode material mixture, and an isolation portion formed between the positive electrode portion and the negative electrode portion. Between the plurality of electrode layers disposed adjacent to each other, the positive electrode portion and the negative electrode portion are disposed so as to face each other, and the isolation portions are disposed so as to face each other.
