  "textContent": "The present invention provides a nonaqueous electrolyte secondary battery that can be charged at high voltage and suppress capacity deterioration after charged storage in a high temperature environment. A nonaqueous electrolyte secondary battery 10 includes a positive electrode sheet 11, a negative electrode sheet 12, a nonaqueous electrolyte, and a separator 13, and the positive electrode active material has a potential of 4.35 to 4.60 V based on lithium. The positive electrode sheet 11 has a surface provided with an inorganic particle layer. The separator 13 has an average pore size of 0.15 µm or more and 0.3 µm or less. It is preferable that the inorganic particle layer provided to the surface of the positive electrode sheet 11 contain titanium oxide or aluminum oxide.",
