ABSTRACT:
A thin film lithium battery is provided which can realize a high yield by solving various problems caused by a pin hole formed in a solid electrolyte layer.A thin film lithium battery according to the present invention is a thin film lithium battery in which a positive electrode layer20, a negative electrode layer50, a solid electrolyte layer40provided therebetween, and a collector10electrically connected to at least one of the positive electrode layer20and the negative electrode layer50are laminated to each other. When this battery is viewed in plan along the lamination direction of the above individual layers, the positive electrode layer20and the negative electrode layer50are disposed at positions so as not to be overlapped with each other. By the structure as described above, even if a pin hole is formed in the solid electrolyte layer40, short-circuiting between the two electrode layers20and50, which is caused by this pin hole, can be prevented.
