<p>PROBLEM TO BE SOLVED: To provide a flat type secondary battery capable of electrically connecting connection tabs of respective electrodes to each other even if a metal foil of a current collector constituting the electrode is constituted of metal which is thin and weak against heat when an electrode group of a laminated structure is constituted.SOLUTION: Disclosed is a flat type secondary battery 1 which has an electrode group 5 formed by arranging a positive electrode plate 7 and a negative electrode plate 8 opposed to each other via a separator 9, and an electrolytic solution 6, and in which the electrode group 5 and the electrolytic solution 6 are included in an outer case 2 in which a first plane 2a serves as an electrode terminal having positive polarity and a sealing case 4 in which a second plane 4a opposite to the first plane 2a serves as the electrode terminal having negative polarity. The positive electrode plate 7 and the negative electrode plate 8 have connection tabs whose respective mutual electrode plates are connected to each other, and the mutual connection tabs are connected by anisotropic conductive films 10a, 10b.</p> |
