Claim 5:
6. A transducer for electrochemical measurement of a target substance generated by a specimen contained in an electrolytic solution, the transducer comprising:
a large-scale integration chip;
an electrolytic solution well which accommodates the electrolytic solution, a hole at a bottom of which being stopped with a top surface of the large-scale integration chip;
first electrodes arranged in an array and located in a sensor region that is formed in the top surface of the large-scale integration chip, the sensor region facing an inside of the electrolytic solution well; and
at least one second electrode located in the sensor region, by which each of the first electrodes is surrounded,
wherein the large-scale integration chip comprises switches respectively connected to each of the first electrodes and the at least one second electrode.
