  "textContent": "A nonaqueous electrolyte secondary battery includes a positive electrode plate having a positive electrode active material layer formed on a positive electrode core, a negative electrode plate having a negative electrode active material layer formed on a negative electrode core, and a flat-shape wound electrode body in which the positive electrode plate and the negative electrode plate are wound through a separator. Further, a protective layer is formed on the positive electrode active material layer or the negative electrode active material layer. The protective layer contains ceramic particles and a binder, and the average particle diameter (D50) and the average particle diameter (D90) of the ceramic particles are 1.0 μm to 1.8 μm and 3.0 μm to 5.0 μ, respectively.",
