In a nonaqueous-electrolyte secondary battery, it prevents short circuit between a positive electrode and a negative electrode even if pressure from the outside, or stress generated by folding is applied thereon, during the battery is manufactured, or when the battery is used as a product. In the lithium ion battery comprising a laminating structure, in which the positive electrode, gel-type macromolecular solid electrolyte layers in the positive electrode, separators, gel-type macromolecular solid electrolyte layers in the negative electrode, the negative electrode are laminated, two covering members are provided in ends of the positive electrode and the negative electrode, two pair of covering members are provided in a position on one electrode in either one of the positive electrode or the negative electrode oppose to the positions, in which the two covering members are provided. Thereby, electrical short circuit between the positive electrode and the negative electrode, generated by seclusion change or pressure, which is applied to the laminating structure from the outside, can be prevented. <IMAGE> |
