Abstract
A method for producing a nonaqueous secondary battery electrode of the present invention includes: a coating formation step of applying an electrode mixture layer-forming composition containing an active material and a solvent onto a current collector so as to form a coating of the composition; an introducing step of introducing the current collector with the coating in a drying oven; and a drying step of drying the coating by irradiating the coating in the drying oven with near-infrared electromagnetic waves having a peak of a wavelength distribution in a range of 1 to 5 μm so as to form an electrode mixture layer. In the drying step, a temperature of the coating is set higher than a temperature in the drying oven by a range of 65° C. to 115° C.
