A nonaqueous-electrolyte secondary battery capable of maintaining satisfactory adhesion of an electrode terminal lead of a heat-welding portion of a nonaqueous-electrolyte secondary battery packaging material without deteriorating moisture permeability. The battery element was accommodated in a packaging material made of a laminated film, so that the battery element was encapsulated by thermal welding. The electrodes constituting the battery element and the electrode terminal leads electrically conductively exposed to the outside of the nonaqueous-electrolyte secondary battery through the heat-welding portion. A portion of the electrode terminal lead corresponding to the heat-welded portion was coated with a coating layer made of the same resin as the resin forming the innermost layer of each laminated film and the olefin adhesive layer containing the titanate coupling material.n n n n Moisture Resistance, Moisture Resistance, Non-Aqueous-Electrolyte, Gel Electrolyte, Solid Electrolyte, Secondary Battery, Titanate Coupling Material, Olefin Adhesive Layer, Coating Layer, Adhesiveness |
