  "textContent": "A nonaqueous electrolyte secondary battery provided with a positive electrode, a negative electrode and a nonaqueous electrolyte. An electrode mixture layer of the positive electrode contains: first lithium metal composite oxide particles that are non-aggregated particles which have a volume-based median diameter of from 2 μm to 10 μm; and second lithium metal composite oxide particles that are secondary particles, in each of which primary particles having an average particle diameter of from 50 nm to 2 μm aggregate, and which have a volume-based median diameter of from 10 μm to 30 μm. With a first region and the second region sequentially halved from the surface side of the positive electrode mixture layer, the content of the first lithium metal composite oxide particles in the first region is higher than the content of the first lithium metal composite oxide particles in the second region.",
