PROBLEM TO BE SOLVED: To administer a suitable water electrolysis treatment by flowing a large amount of raw water for water electrolysis into the reaction area of a water electrolytic cell while suppressing the power of a pump.SOLUTION: A water electrolytic cell 10 comprises a separator 31 situated on the hydrogen-electrode side and a separator 41 situated on the oxygen-electrode side, which are provided on both sides of an electrode body 21 comprising power feeders arranged on both sides of an electrolyte film. The water electrolytic cell 10 is rectangular, placed oblongly to the vertical direction, and laminated in the horizontal direction. The raw water for water electrolysis is supplied from connecting holes 24, 34, and 44 that are arranged along the lower long side of the water electrolytic cell 10 toward connecting holes 23, 33, and 43 that are arranged along the upper long side.SELECTED DRAWING: Figure 2
