Abstract

In one aspect, the present disclosure relates to an enzyme sensor (1) for measuring a concentration of a subject substance in a solution containing the subject substance. The enzyme sensor (1) includes: a working electrode (2) and a standard electrode (3) , each of which may be brought into contact with the solution; an enzyme and a redox substance capable of being reversibly oxidized and reduced, the enzyme and the redox substance being each immobilized onto the working electrode (2); and a dV/dt output mechanism (9) capable of outputting, with time, a time differential value dV/dt of a potential difference between the standard electrode (3) and the working electrode (2) caused by changes in concentrations of an oxidized form and a reduced form of the redox substance resulting from a reaction between the subject substance and the enzyme. The potential difference shifts to higher values when the redox substance is oxidized by the reaction between the subject substance and the enzyme, or the potential difference shifts to lower values when the redox substance is reduced by the reaction.
