Abstract

This all-solid-state battery is provided with a battery container, and a power generation element accommodated within the battery container. The battery container includes a concave container and a sealing body. The concave container and the sealing body are made of a metal material. The concave container is provided with a bottom surface part and a side wall part. An opening of the concave container is sealed with the sealing body. The sealing body is provided with an electrode terminal that is drawn out of the interior of the concave container. The sealing body and the electrode terminal are insulated with a hermetic seal, and bonded in an air-tight fashion. The power generation element is made of an electrode laminate including a positive electrode, a negative electrode, and a solid electrolyte layer arranged between the positive electrode and the negative electrode. Arranged between the electrode laminate and the electrode terminal is a current collector member that covers an upper surface of the electrode laminate and electrically connects to the electrode terminal. A pressing member is arranged between the current collector member and the sealing body and / or between a lower surface of the electrode laminate and the concave container, and the electrode laminate and the current collector member are pressed by a pressing force of the pressing member.
