Abstract

The battery of the invention has a positive-electrode layer, a negative-electrode layer, and an electrolytic layerthrough which ionic conduction is performed between the two electrode layers. In this battery, the positive-electrode layerand the negative-electrode layerare laminated with each other and an insulating layeris placed between the positive-electrode layerand the negative-electrode layer. The insulating layerhas an area smaller than that of one of the positive-electrode layerand the negative-electrode layerand larger than that of the other. There is no place where the positive-electrode layerand the negative-electrode layerface each other through only the electrolytic layer. Even when the electrolytic layerhas a pinhole, the presence of the insulating layerbetween the positive-electrode layerand the negative-electrode layercan suppress short-circuiting between the positive- and negative-electrode layers.
