PURPOSE:To raise the detection sensitivity, and also, to stabilize the detecting reaction by placing successively and repeatedly reaction parts of each electrode, in the electrochemical sensor in which a solid-state electrolytic layer is provided among a working electrode, a counter electrode and a reference electrode. CONSTITUTION:On an insulating electrode 1, reaction parts 20, 30 and 40 for executing an electrochemical action and a working electrode 2, a counter electrode 3 and a reference electrode 4 consisting of terminal parts 21, 31 and 41 which are connected to an external circuit are provided, and the upper part of each reaction part 20, 30 and 40 and the parts among them are covered with a slid-state electrolytic layer 6. The reaction parts 20, 30 and 40 of the working electrode 2, the counter electrode 3 and the reference electrode 4 consist of those which are formed in a thin spiral line shape, and these spiral-like reaction parts 20, 30 and 40 have the same center, and also, placed at a prescribed interval between each other. The outside peripheral ends of each reaction part 20, 30 and 40 are connected to the rectangular surface-like terminal parts 21, 31 and 41, and can be connected easily to the external circuit. |
