To provide an electrolytic water production apparatus for reducing production cost of the apparatus, with a plurality of electrolytic cells.

In this electrolytic water production apparatus, an electrode plate used in one electrolytic cell is used also in another electrolytic cell. The electrolytic water production apparatus includes: an electrolysis part including a plurality of electrolytic chambers (diaphragm electrolytic chambers and diaphragmless electrolytic chambers) formed by water-tightly partitioning the inside of a tank by at least three electrode plates parallel to one-side walls facing each other of the tank; wiring alternately connecting at least the three electrode plates to an anode and a cathode of a DC power supply; an electrolytic raw water supply pipe for supplying electrolytic raw water to the electrolytic chambers; and an electrolytic water take-out pipe for taking out the electrolytic water from the electrolytic chambers to the outside.
