PROBLEM TO BE SOLVED: To obtain an alkaline ion water serving as cleaning water having high washing power even when chemically synthesized substance is not used. SOLUTION: In an alkaline ion water preparing device 200, water entering from a water line is sent to a water cleaner 202 wherein musty smell, chlorine, trihalomethane or the like are removed, is sent to an electrolytic bath 203 composed of an anode, a cathode and a barrier membrane, and is electrolyzed to bias pH of water respectively on the anode side and cathode side via the barrier membrane, whereby two kinds of waters of acidic water and alkaline water are prepared. The alkaline ion water going out of the minus side flows toward a dedicated faucet for alkaline ion water, the acidic ion water going out of the plus side is discarded. A nano-bubble generating device is constituted of a water suction port, a nano-bubble generating means which blows air bubbles into water sucked through the water suction port and a discharge port for discharging water containing the nano-bubbles. The alkaline ion water in a water tank is circulated by using the nano-bubble generating device and thereby, the alkaline ion water containing nano-bubble water is prepared.
