Zusammenfassung:	To provide a means capable of suppressing the generation of cracks in an electrode active material layer in the production of an electrode for a non-aqueous electrolyte secondary battery.Provided is a method for producing an electrode for use in a non-aqueous electrolyte secondary battery, including a current collector and an electrode active material layer including an electrode active material, arranged on a surface of the current collector, and a dispersion is by mixing the electrode active material, a binder formed of polyvinylidene fluoride (PVdF), a first solvent in which the polyvinylidene fluoride (PVdF) is not dissolved, and a second solvent in which the polyvinylidene fluoride (PVdF) can be dissolved. Then, an electrode active material slurry is prepared by removing the second solvent from the obtained dispersion. Then, a coating film is formed by coating the obtained electrode active material slurry on the surface of the current collector, thereby producing an electrode.
