Abstract: A method for producing an alkali metal/alkaline earth metal hydroxide includes: subjecting a solution containing RA—COOMB and/or (RA—COO)2MC and water to an electrochemical reaction to cause a Kolbe electrolysis reaction at an anode to generate at least RA—RA, carbon dioxide, and an MB+ ion and/or MC2+ ion; and neutralizing the MB+ ion and/or MC2+ ion by using an OH− ion generated by electrolysis of water at a cathode. RA represents a hydrocarbon group, MB represents an alkali metal, and MC represents an alkaline earth metal.
