Positive electrode for nonaqueous electrolyte secondary battery, and nonaqueous electrolyte secondary battery

A positive electrode for a non-aqueous electrolyte secondary battery is provided with a positive electrode core and a positive electrode mixture layer formed on the surface of the positive electrode core. The positive electrode mixture layer contains at least a positive electrode active material and lithium phosphate. The positive electrode active material contains: a first positive electrode active material having a Ni content of 50-65 mol% with respect to the total molar weight of metal elements other than Li; and a second positive electrode active material having a Ni content of 45 mol% or less relative to the total molar amount of metal elements other than Li. The ratio of the first positive electrode active material to the second positive electrode active material in the positive electrode mixture layer is 80: 20 to 50: 50 by mass ratio. 非水电解质二次电池用正极具备：正极芯体、和形成于正极芯体的表面的正极复合材料层。正极复合材料层至少包含正极活性物质和磷酸锂，正极活性物质包含：相对于除Li之外的金属元素的总摩尔量的Ni含有率为50摩尔％～65摩尔％的第1正极活性物质；和相对于除Li之外的金属元素的总摩尔量的Ni含有率为45摩尔％以下的第2正极活性物质，正极复合材料层中的
