PROBLEM TO BE SOLVED: To produce water which can be drunk and used for sterilization.SOLUTION: Tap water or water having water quality similar to or higher than tap water in which sodium chloride is dissolved (hereafter "use water") is flown through an intermediate chamber 4 of a three chamber-type electrolysis vessel 6 comprising an anode chamber 3, the intermediate chamber 4 and a cathode chamber 5, use water 9 to be electrolyzed is flown in the anode chamber 3 at an adjusted flow rate, and electrolyzed and pH-adjusted to generate acidic electrolyzed water 10 having a pH of 2.5-3.1, use water 11 to be electrolyzed is flown in the cathode chamber 5 at an adjusted flow rate and electrolyzed to obtain alkaline electrolyzed water 12, use water 13 not electrolyzed is merged with the obtained alkaline electrolyzed water 12 outside the three chamber-type electrolysis vessel 6 to dilute them and adjust a pH value to generate diluted alkaline electrolyzed water 14 with a pH value of 11.0 to 11.6, besides the pH value is adjusted to obtain acidic electrolyzed water 10, which is mixed with the diluted alkaline electrolyzed water 14 at a volume ratio of 10:2 to 6.5 to thereby produce water of a pH of 5.9 to 6.8.SELECTED DRAWING: Figure 1 【課題】飲用することもできるし、また殺菌にも使用することができる水を製造する。【解決手段】陽極室３、中間室４と陰極室５を備えた三室型電解槽６の中間室４に塩化ナトリウムを溶解した水道水または水質が水道水と同等以上の水（以下、「使用水」という）を通水し、陽極室３内に電解処理をする使用水９を流量を調整して通水し、電解処理をしてｐＨ値を調節しｐＨ２．５〜３．１の酸性電解水１０を生成する一方、陰極室５内に電解処理をする使用水１１を流量を調整して通水して電解処理をし、得られたアルカリ性電解水１２に、電解処理をしていない使用水１３を、三室型電解槽６外において合流して希釈してｐＨ値を調節し、ｐＨ１１．０〜１１．６の希釈されたアルカリ性電解水１４を生成し、更に前記ｐＨ値を調節した酸性電解水１０と希釈されたアルカリ性電解水１４とを１０：２〜６．５の容積比で混合して、ｐＨ５．９〜６．８の水を製造する。【選択図】図１
