A method for producing an electrode sheet includes heating before pressing to heat the electrode sheet to soften or melt binder particles contained in an electrode mixture layer and roll-pressing the electrode sheet heated in the heating before pressing by use of first and second rolls. In the roll-pressing, the temperature of an outer peripheral surface of a first roll with which an outer surface of the electrode mixture layer of the electrode sheet contacts is set lower than the temperature of an outer peripheral surface of the second roll, and the electrode sheet is roll-pressed so that an adhesive strength of binder particles in the electrode mixture layer to the first roll is reduced lower than an adhesive strength of the binder particles to a current collecting foil.
