PROBLEM TO BE SOLVED: To provide an electrode structure for enzyme sensors, having a working electrode provided with an enzyme layer having a uniform layer thickness and a prescribed area, and an enzyme sensor provided with the electrode structure for enzyme sensors, and to provide an artificial pancreas device having the enzyme sensor.SOLUTION: In the electrode structure for enzyme sensors provided with the working electrode and a reference electrode on a substrate, the working electrode includes an electrode layer formed on the substrate, an enzyme layer formed on the electrode layer, and a dam part for surrounding the electrode layer and the enzyme layer. The dam part is formed, in such a way as to hold an enzyme solution as horizontally maintaining the surface of the enzyme solution when the enzyme solution, a raw material of the enzyme layer, is housed in the dam part prior to the formation of the enzyme layer; and the enzyme sensor has the electrode structure for enzyme sensors, and the artificial pancreas device has the enzyme sensor. |
