Abstract

A mineral-water producing apparatus that includes: an electrolytic bath to which raw water, such as city water, is supplied; a mineral eluting material(s) arranged in the electrolytic bath; and electrodes for applying DC voltage with which the water in the electrolytic bath is electrolyzed so that a mineral element(s) is eluted from the mineral eluting material (s), where the mineral water produced in the electrolytic bath is delivered to the outside thereof, characterized in that the apparatus further includes: a pH sensor which detects the pH of the raw water; and a controller which controls the conducting time duration for the electrodes based on the detection signal from the pH sensor. Thus, mineral water having a desired mineral concentration is produced.
