<p> Provided is a biosensor with which it is possible to accurately measure a variety of blood components, especially blood-glucose concentration, even if hematocrit levels fluctuate. This problem was addressed by providing a biosensor (10) comprising an electric insulating substrate (102), an electrode system (104) having a working electrode (1042) and an opposing electrode (1044) formed on the electrical insulating substrate (102), and a reagent layer (204) containing an oxidoreductase and a redox mediator, wherein the electrode system (104) is made from metal, a hydrophilic polymer layer (202) is formed on the electrode system (104), and the reagent layer (204) is formed outside the hydrophilic polymer layer (202) in such a manner that the oxidoreductase and the redox mediator shift to the hydrophilic polymer layer (202) after coming into contact with the sample.</p> |
