An electrode manufacturing method which can form a flat short-circuit prevention coating film (solid polyelectrolyte layer) having a uniform thickness and prevent short circuits from occurring in an electrochemical device is provided. The electrode manufacturing method comprises a first step of applying an active material layer coating material containing an active material particle, an active material layer binder, and a first solvent to a current collector so as to form a coating film made of the active material layer coating material; a second step of applying a second solvent to the coating film; and a third step of applying a solid polyelectrolyte layer coating material containing a solid polyelectrolyte, a solid polyelectrolyte layer binder, and a third solvent to the coating film coated with the second solvent. The first solvent is a good solvent for the active material layer binder, the second solvent is a poor solvent for the solid polyelectrolyte layer binder, and the third solvent is a good solvent for the solid polyelectrolyte layer binder.
