Disclosed is a positive electrode for lithium secondary batteries, which comprises a conductive layer formed on the surface of a positive electrode collector, and an active material layer formed on the conductive layer. The conductive layer contains at least one water-insoluble polymer which is soluble in an organic solvent and functions as a binder, and a conductive material. The active material layer contains at least one aqueous polymer which is soluble or dispersible in water and functions as a binder, a positive electrode active material and a conductive material. The average particle diameter (DA) of the conductive material in the conductive layer is smaller than the average particle diameter (DB) of the conductive material in the active material layer. |
