Abstract: One of the objects of the present invention is to suppress mixing of a first layer and a second layer while forming the second layer before drying the first layer when manufacturing the electrode for the secondary battery in which the first layer and the second layer are laminated on the current collector. A method for manufacturing an electrode used as a positive electrode and a negative electrode of a secondary battery according to the present invention comprises applying a first layer slurry to a surface of a current collector, applying a second layer slurry on the first layer slurry before the first layer slurry is dried, and drying the first layer slurry and the second layer slurry after applying the first layer slurry and the second layer slurry to obtain a laminated structure in which a first layer and a second layer are laminated in this order on the current collector. A viscosity of the first layer slurry is 12000 mPa·s or more, and/or a viscosity of the second layer slurry is 4000 mPa·s or more when the viscosities of the first layer slurry and the second layer slurry are measured at 25° C. with a shear rate of 1/sec.
