PROBLEM TO BE SOLVED: To make it possible to rapidly measure the substrate concentration of even trace amount of a liquid to be inspected and to reduce the size. SOLUTION: An operating electrode 13 is provided on one surface of an open-cell porous board 12 in which an enzyme is immobilized, and a counter electrodes 14 are provided on the other surface, and an opening 18 is formed on the electrode 14 side. A board 15 and an insulating film 16 are sequentially formed on the outer surface of the electrodes 14. An insulating film 17 is formed on the entire one side surfaces of the electrode 13 and the board 12. A liquid to be inspected introduced from the opening 18 rapidly permeates between the electrodes 13 and 14 via the board 12 to be able to measure the substrate concentration. |
