PURPOSE:To prevent any crack and improve the preservation performance of a thin battery, which is sealed by fusing the peripheries of sealing plates with soldering materials, by using a given ceramic as an insulating material, and using a given cobalt-nickel-iron alloy plate as the sealing plate. CONSTITUTION:A generation element 1 consisting of a solid electrolyte 2, a negative electrode 3 and a positive electrode 4 is hermetically sealed with a ring- like insulating material 5, and sealing plates 6 and 7 also serving as electrode terminal plates, thereby a thin battery being constituted. The plate 5 and the plates 6 and 7 are provided with metal plating layers 12-15. Soldering materials 8 and 9 are interposed between the layers 12 and 14 and between the layers 13 and 15, respectively, before the battery is hermetically sealed by fusion. The insulating material 5 is made of an aluminum oxide system ceramic. The plates 6 and 7 are prepared from a cobalt-nickel-iron alloy plate consisting of 18wt% of cobalt, 28wt% of nickel and 54wt% of iron. |
