PROBLEM TO BE SOLVED: To provide a manufacturing method and a manufacturing device for a battery electrode sheet capable of reducing cost, and efficiently and safely drying the electrode sheet. SOLUTION: This manufacturing device comprises a running rollers 1a, 1b for running a tape-like support body 2 in a constant direction, a pasty electrode mix vessel 3 for passing and running the tape-like support body 2 and coating the main surface of the tape-like support body 2 with the pasty electrode mix 4, a coating amount control means 5 disposed in the running direction of the tape-like support body 2 for controlling the amount of the applied pasty electrode mix, and a tunnel-shaped drying oven 9 for drying through which a tape- like support body 2' controlled in the applied amount runs. The tunnel-shaped drying oven 9 comprises a first region having hot air blast nozzles 10a and 10b for jetting hot air to the applied surface of the electrode mix of the running tape-like support body 2', a second region 9b that is connected to the first region and is constricted, and has an orifice structure 9b' for increasing hot air speed, and a third region 9c that is connected to the second region 9b and has a hot air exhaust port for discharging the hot air. |
