  "textContent": "A secondary battery positive electrode includes a belt-shaped positive electrode current collector with two regions and a positive electrode mixture thereon. The first region being at both ends and the second region is a central area. The positive electrode mixture layer includes a first positive electrode mixture layer carried on the first region and a second positive electrode mixture layer carried on the second region. The positive electrode mixture layer includes a first positive electrode mixture layer on the first region and a second positive electrode mixture layer on the second region. An average particle diameter D of a first positive electrode active material of the first positive electrode mixture layer is 1 μm or more and 7 μm or less. An average particle diameter D of a second positive electrode active material of the second positive electrode material layer is 9 μm or more and 30 μm or less.",
