description A functional water concentration sensor (1) includes: a light source (10) which emits ultraviolet light (11); a container (20) capable of holding functional water (90) having a pH between 6 and 9, inclusive, and containing hypochlorous acid and hypochlorite dissociated from the hypochlorous acid; a light-receiving element (30); and a signal processor (40). The signal processor (40) calculates the concentration of the hypochlorite in the functional water (90) on the basis of the output signal, calculates the percentages of the hypochlorous acid and the hypochlorite in the functional water (90) on the basis of the pH of the functional water (90) and dissociation constant pKa of the hypochlorous acid, and calculates the concentration of the hypochlorous acid in the functional water (90) on the basis of the calculated hypochlorite concentration and the calculated percentages.
