PROBLEM TO BE SOLVED: To provide an easy manufacturing method high quality stacked battery electrode in which the occurrence of warp is hardly allowed, and no coming-off of a lead portion is allowed. SOLUTION: The method is for manufacturing a stacked battery electrode composed of a collector heating a thin plate-like collecting portion and a lead portion protruding from the peripheral edge of the collecting portion, and active material formed at least on one face of the collector. The lead portion is formed at least at one side end portion in the width direction of belt-like metal plate material to be the collector, and first the active material is continuously applied to at least one side face of the metal plate material except the whole or the main portion of the lead portion. Next, this active material-applied portion is rolled into predetermined thickness by a roll press, and finally is cut out into a collector shape so as to form an electrode. |
