  "textContent": "A non-aqueous electrolyte secondary battery disclosed herein includes a positive electrode, a negative electrode, and a non-aqueous electrolyte. The positive and negative electrodes each include a current collector and a mixture layer formed on the surface of the current collector. The current collector includes a resin layer and metallic foils provided on both surfaces of the resin layer in at least one of the positive and negative electrodes. A surface of the metallic foils on which the mixture layer is formed is roughened. Furthermore, the average X (μm) of the thicknesses at the thinnest parts and the average Y (μm) of the thicknesses at the thickest parts of the metallic foil determined based on a plurality of obtained sectional SEM images in a stacked direction of the resin layer and the metallic foils satisfy the following relationship: 0.1 μm",
