[Problem] To provide: a positive electrode for nonaqueous electrolyte secondary batteries, which is capable of improving storage characteristics and cycle characteristics in a high-temperature high-voltage state; a method for producing the positive electrode for nonaqueous electrolyte secondary batteries; and a nonaqueous electrolyte secondary battery which is provided with the positive electrode. [Solution] A positive electrode for nonaqueous electrolyte secondary batteries, which is provided with: a positive electrode mixture layer that contains a position electrode active material, a conductive agent and a binder; and a porous inorganic particle layer that is formed on the surface of the positive electrode mixture layer. The porous inorganic particle layer contains at least one substance that is selected from among sodium hexametaphosphate, sodium pyrophosphate, trisodium phosphate and disodium hydrogen phosphate. |
