That is, the pressure reducing valve 132a is opened, the pressure inside the chamber 140 is reduced, and the bubbles remaining in the electrode 3 and the bubbles dissolved in the electrolyte solution W are removed. Next, after the pressure reducing valve 132a is closed, the atmosphere release valve 133a is opened, and the inside of the chamber 140 is returned to the atmospheric pressure. Then, the atmosphere release valve 133a is closed.

Next, the chamber 140 is pressurized. That is, the pressurizing valve 134a is opened to pressurize the inside of the chamber 140 to accelerate the impregnation of the electrode 3 with the electrolytic solution W. Next, after closing the pressurizing valve 134a, the atmosphere release valve 133a is opened, and the inside of the chamber 140 is returned to the atmospheric pressure.
