LAYERED SECONDARY BATTERY

PROBLEM TO BE SOLVED: To provide a layered secondary battery which is excellent in charge and discharge characteristics and heat radiation characteristics. SOLUTION: In the layered secondary battery, flat plate-shaped positive electrodes and negative electrodes, wherein either of the positive electrodes and negative electrodes is increased one piece rather than the other, are alternately laminated via separators, mutual metal plate-shaped bodies arranged by directly keeping in contact with both end faces of laminates in the laminated direction made of battery elements, wherein positive electrode pulling-out terminals of the positive electrodes and negative electrode pulling-out terminals of the negative electrodes are respectively connected, are combined with a combination member, the laminates are held and retained at both end faces, and the battery elements held and retained by the metal plate-shaped bodies are sealed by a film-shaped envelope material.
