PROBLEM TO BE SOLVED: To provide a light-weight and small on-vehicle secondary battery, especially one having a plurality of it contained in an outer covering container. SOLUTION: This battery L comprises a battery constitution 1, having a positive electrode current collector 111 and a negative electrode current collector 121, a flexible battery container 3 in which the construction is contained, a positive electrode terminal layer 41 formed on a surface of the container and a negative electrode terminal layer 42 and has the positive electrode current collector and the positive electrode terminal layer, as well as the negative electrode current collector and the negative electrode terminal layer connected electrically. Especially it is preferable that the battery container be a flat plate container made of an impermeable film, such as aluminum laminated film and a positive electrode terminal layer is formed on one face of the container and the negative electrode terminal layer on the other face. A plurality of the battery is contained in the outer covering container made of resin and the positive electrode terminal layer of one battery contacts the negative electrode terminal layer of the other adjoining battery for connecting them in series, and thereby the light and small on-vehicle secondary battery can be provided. |
