Laminated thin film battery

摘要

Disclosed is a laminated thin film battery which is capable of exhibiting a high capacity and does not require a separate barrier to be formed on a surface after lamination. A first thin film battery and a second thin film battery, in which cathode current collectors and anode current collectors are formed on first surfaces, are laminated in such a type that the respective first surfaces face each other. The cathode current collectors of the first thin film battery and the second thin film battery are electrically connected to a cathode terminal, and the anode current collectors of the first thin film battery and the second thin film battery are electrically connected to an anode terminal.
