Abstract
A reagent layer of a sensor contains as a mediator a quinone compound having a hydrophilic functional group, phenanthrenequinone, and/or a phenanthrenequinone derivative. The quinone compound has a lower redox potential than a conventional mediator, so interfering substances have less effect on detection results with this sensor.
