    • PROBLEM TO BE SOLVED: To form an active material layer accurately at positions on both sides of a metal foil facing each other, by preventing uneven thickness at the end of the active material layer, even if the active material layer is formed intermittently on a strip metal foil.SOLUTION: An active material layer 17 is formed intermittently by coating one side of a metal foil 11 with a slurry S containing an active material, by using a strip metal foil 11 having a carbon coat layer on both sides. Subsequently, when coating the other side with a slurry S containing an active material, a mark located corresponding to each active material layer 17 formed intermittently on one side is detected by a sensor 19. With reference to that position, the position of the end of an active material layer 17 formed on one side is determined, and the slurry S is applied by determining the position of coating the other side intermittently with the slurry S for each active material layer.
