In a water treatment apparatus, the time for treatment after water to be treated is introduced into an electrolytic bath is reduced. The water to be treated in a reservoir is subjected to electrolysis at a first electrolytic bath. Electrolysis is carried out at respective first and second electrolytic baths. By the electrolysis at the second electrolytic bath, hypochlorous acid is generated from chloride ions at the anode side. The solution subjected to electrolysis at the second electrolytic bath is mixed at a predetermined site of the pipe connected between the reservoir and the first electrolytic bath with the water output from the reservoir via a pipe prior to introduction into the first electrolytic bath. Accordingly, the water subjected to electrolysis at the first electrolytic bath can be sterilized in advance by the hypochlorous acid generated by electrolysis at the second electrolytic bath.
