A method for forming an electrode for a battery includes the step of rotating a gravure roll while allowing the gravure roll to abut against the surface of an electrode, thereby applying a coating fluid serving as a precursor of a porous layer on the surface of the electrode. In this step, part of the coating fluid applied to the surface of the electrode is continuously removed by allowing a scraper to abut against the surface of the electrode, and the width of a part of the scraper abutting against the surface of the electrode is adjusted according to variations in the width of each of linear portions of the porous layer left after the removal of the part of the coating fluid.
