A non-aqueous electrolyte secondary battery in which, even when a current collector terminal is welded to a current collector part, separation of the constituent materials and detachment of the mixture layer are effectively suppressed. A method by which the secondary battery can be produced with high productivity and at lower cost. A non-aqueous electrolyte secondary battery having a layered structure in which power-generating components including an electrode are layered. The electrode includes an electrode current collector and an electrode mixture layer provided in a part of the electrode current collector, which includes a current collector part not provided with the electrode mixture layer of the electrode current collector, and the current collector part includes a weld section welded to the current collector part of another electrode current collector adjacent in a layering direction. The current collector part includes a vibration-absorbing member between the weld section and the electrode mixture layer.
