PURPOSE:To enhance a wide linear responding range, sensitivity, accuracy and reliability by sequentially laminating an electrode, an enzyme solidified film obtained by solidifying enzyme to be selectively reacted with substance to be sensed, and a porous polymer film having average pre diameter within a specific numeric value. CONSTITUTION:An operation electrode 2 and an opposite electrode 3 formed on an insulating board 1 are covered with glucose oxidase, and a polycarbonate film 5 having 0.03mum of average pore size is placed thereon to form a glucose oxidase solidified film 4. Thus, since rapid response is exhibited for glucose solution having predetermined concentration and it is not necessary to remarkably reduce the average pore size of a porous polymer film even with sample liquid having low dissolving oxygen concentration, excellent reproducibility is obtained, sensing accuracy is improved. |
