PROBLEM TO BE SOLVED: To provide a device of manufacturing a battery electrode suitable for achieving a higher capacity of a battery while a mixture crack or the like is hard to occur in the electrode material after a drying process even if the electrode material is thickly coated on a current collector foil of a vehicular battery.SOLUTION: Disclosed is a device of manufacturing a battery electrode P including a drying step in which, after a slurry-like paste obtained by dissolving an electrode material into a solvent is coated on the upper surface of a web-like current collector foil S, the coated paste is dried in a drying oven 10. In the drying step, in a constant drying region (B) where the solvent linearly decreases, a curvature part PW is arranged in which the coated surface side of the current collector foil is curved upward in a feeding direction. |
