Electrolyzed water producing method and apparatus are provided which are capable of producing electrolyzed water having a desired property irrespective of the quality of raw water supplied and the like while allowing the size and weight of the apparatus and the cost to be reduced by limiting the capacity of an electrolysis power source. The electrolyzed water producing method includes: circulating an aqueous electrolyte solution to a first electrolytic chamber (3a) of a pair of electrolytic chambers (3a, 3b) opposed to each other across an intervening ion permeable diaphragm (2) while supplying raw water to the second electrolytic chamber (3b); and applying a predetermined voltage to a pair of electrodes (7a, 7b) disposed in the respective electrolytic chambers (3a, 3b) with the diaphragm (2) intervening therebetween, to electrolyze the raw water and the aqueous electrolyte solution, thereby producing electrolyzed water in the second electrolytic chamber (3b). When an electrolytic current generated by the electrolysis is less than a predetermined current at a point in time at which a first predetermined time has elapsed from start of the electrolysis, with the electrolyte being supplied to the aqueous electrolyte solution, supply of the electrolyte is increased until the electrolytic current is equal to or greater than the predetermined current after lapse of the first predetermined time, with the voltage applied across the pair of electrodes (7a, 7b) being kept at the predetermined voltage.
