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 layer, a negative electrode layer, a solid electrolyte layerprovided therebetween, and a collectorelectrically connected to at least one of the positive electrode layerand the negative electrode layerare laminated to each other. When this battery is viewed in plan along the lamination direction of the above individual layers, the positive electrode layerand the negative electrode layerare 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 layer, short-circuiting between the two electrode layersand, which is caused by this pin hole, can be prevented.
