description PROBLEM TO BE SOLVED: To provide a battery electrode with high bulk density and a smooth surface through less pressing number and light pressing by preheating a laminate prepared by applying an electrode mix to one side or both sides of a metal foil current collector, before it is pressed or heat-roll pressed. SOLUTION: A laminate 7 is successively fed from a winding out roll 1, where the laminate 7 is wound and stacked, and sent to a preheating part 3 through a guide 2. The laminate 7 is passed on a plurality of small diameter heating drums or on a large diameter heating drum, having the dimension capable of entering the preheating part 3, heated once, then sent to a heat press roll 4, without the temperature is not being lowered much. The laminate 7 is heated and at the same time pressed with the heat press roll 4 comprising two heating rolls and a hydraulic cylinder 6. The heated and pressed laminate 7 is wound with a winding roll 5.
