FLAT SOLID-STATE BATTERY AND METHOD FOR MANUFACTURING SAME

A flat-shaped all-solid battery described in this application includes a battery container constituted by an outer can and a sealing can and a stack which a positive electrode, a solid electrolyte layer, and a negative electrode are stacked to form. The stack is housed in the battery container. A conductive porous member constituted by a molded body of graphite and having flexibility is disposed between the stack and an inner bottom surface of the outer can or an inner bottom surface of the sealing can. Moreover, in the above flat-shaped all-solid battery, the conductive porous member can be disposed between the stack and the inner bottom surface of the sealing can, and between the stack and the inner bottom surface of the outer can.
