  "textContent": "A nonaqueous electrolyte secondary battery according to the present invention comprises a positive electrode that contains, as positive electrode active materials: a lithium transition metal composite oxide (A) that is configured of secondary particles, in each of which primary particles having an average particle diameter of 0.5 µm or more aggregate, or is configured of substantially one kind of particles, while having a volume-based D50 of from 0.6 µm to 3 µm; and a lithium transition metal composite oxide (B) that is configured of secondary particles, in each of which primary particles having an average particle diameter of 0.3 µm or less aggregate, while having a volume-based D50 of from 6 µm to 25 µm. With respect to the lithium transition metal composite oxide (B), the molar fraction (B2) of Ti with respect to the total number of moles of metal elements other than Li on the surfaces of second particles having a particle diameter smaller than the volume-based D30 is higher than the molar fraction (B1) of Ti with respect to the total number of moles of metal elements other than Li on the surfaces of first particles having a particle diameter larger than the volume-based D70.",
