## Abstract

An electrolyzed water-generating apparatus (1) is provided with: an electrolysis tank (D) equipped therein with a first electrode chamber (Da) with a cathode (6a), a second electrode chamber (Db) with an anode (6b), and a septum (Sp) for partitioning the first electrode chamber (Da) from the second electrode chamber (Db); a first inlet water path (4a), which is connected to the first electrode chamber (Da) and is for supplying raw water to the first electrode chamber (Da) from the outside; a first extraction water path (7a), which is connected to the first electrode chamber (Da) and is for extracting electrolyzed hydrogen water generated in the first electrode chamber (Da) by electrolysis to the outside; and an electric charge-adjusting device (10), which is connected to the electrolysis tank (D) and is for adjusting the electric charge applied on the electrolyzed hydrogen water when performing the electrolysis. The electric charge-adjusting device (10) is characterized in adjusting the electric charge per unit volume of electrolyzed hydrogen water taken from the device by controlling the electrolytic current or electrolytic voltage.
