Abstract
An electrochemical cell includes an all-solid-state electrode body in which a positive electrode layer and a negative electrode layer are laminated together through a solid electrolyte and an exterior body having a cavity in which the electrode body is stored. The exterior body has a first case and a second case which sandwich the electrode body and a sealing member that defines the cavity together with the first case and the second case by joining the first case and the second. The thermal expansion coefficients of the electrode body, the first case, the second case, and the sealing member are all 10×10/° C. or lower.
