  "textContent": "The present invention provides a nonaqueous electrolyte secondary battery which has a reduced risk of short circuiting. A nonaqueous electrolyte secondary battery according to one embodiment of the present disclosure is provided with: an electrode body that is obtained by winding a first electrode and a second electrode, which are belt-shaped and have different polarities from each other, in the longitudinal direction with a separator being interposed therebetween; and an outer casing in which the electrode body is housed. The first electrode has a current collector and a mixture layer that is formed on the surface of the current collector. The surface of the first electrode is provided with an exposure part in which the current collector is exposed, and a protective tape is affixed so as to cover the exposure part and the mixture layer around the exposure part. The protective tape has a base material layer and an adhesive layer, and ends of the adhesive layer are positioned more inside of the protective tape than ends of the base material layer in the longitudinal direction of the first electrode, and are positioned closer to the ends of the base material layer than ends of the exposure part.",
