Abstract

The electrode production method disclosed herein has the steps of: preparing an electrode mix paste that contains at least an active material and a solvent; applying the electrode mix paste onto the surface of a collector; and drying a coating film made up of the electrode mix paste applied on the collector. The step of drying includes a residual heat period, a constant rate drying period, and a falling rate drying period. The coating film is pressed at least one time in the falling rate drying period, and the pressing is carried out under conditions such that film thickness of the coating film is not lower than 80% relative to 100% as the film thickness prior to the pressing.
