(57) [Summary] [PROBLEMS] To increase the speed of extrusion coating of an electrode material, to make the coating layer thinner and more uniform, and to easily set operating conditions, to improve the productivity of sheet-shaped electrode manufacturing and to improve the work efficiency. Provided is a method for manufacturing a sheet-like electrode plate that enables improvement. SOLUTION: An extrusion type liquid injector (7) having a slot nozzle (6) is used to apply an electrode material coating liquid (1). 2) is discharged and applied to a predetermined thickness on the conductive support (1) which is wound around the backup roll (2) and travels. From the discharge port of the extrusion type liquid injector (7), A method for producing a sheet-shaped electrode plate, comprising: providing a decompression chamber (11) for depressurizing an upstream portion of the running supporting body in the vicinity thereof, and applying the coating solution under reduced pressure. |
