105 by separate members or products as metal leaves which form the collectors 101 a and 103 a the generator elements 108 are sealed by storing them in the upper part of the external member 106 and the lower part of the external member 107 the upper part external member 106 and upper part external member 107 for this embodiment can be anything and especially although not shown there is construction from members of flexible sheets of a laminated material for the resin metal thin membrane this sheet shaped member is formed by laminating to the outside from the thin type battery 10 the three layers of the inside resin layer the metal layer and the outside resin layer the inside resin layer that forms this sheet shaped member is formed by resident films that have superior electrolyte resistance and heat sealing such as polyethylene denatured polyethylene polypropylene and denatured polypropylene in addition the metal layer is formed using metal leaf such as for example aluminum the outside resin layer is formed using a resin film that is a superior electrical insulator such as for example polyamide series resins or polyester series resins moreover as shown in fig1 and fig2 because the electrode terminals 104 and 105 are conducting from the sealed external members 106 and 107 and because the sealability of the thin type battery 10 is maintained at the part where there is contact between the electrode terminals 104 and 105 and the external members 106 and 107 it is good to have a seal film that.
