  "textContent": "In a non-aqueous electrolyte secondary battery according to one embodiment of the present invention, a positive electrode () has: a positive electrode core material (); and a positive electrode mixture layer () formed on the surface of the positive electrode core material (). The electrode mixture layer () contains, as a positive electrode active material, first lithium metal composite oxide particles that are non-aggregated particles having a volume-based median diameter of 2-10 μm, and second lithium metal composite oxide particles that are secondary particles that have a volume-based median diameter of 10-30 μm and that are each obtained by aggregation of primary particles having an average particle diameter from 50 nm to 2 μm. The first lithium metal composite oxide particles are contained more in a first region () than in a second region (). A non-aqueous electrolyte contains a diisocyanate compound.",
