Abstract
A drop in measurement accuracy of biosensors, due to interferents in a measurement sample is avoided by an arrangement wherein: a hydrogen peroxide electrode 2 is formed on an insulated base 1, and then a .gamma.-aminopropyltriethoxysilane film 3, an acetylcellulose film 4, a perfluorocarbonsulfonic acid resin film 5, an organic macromolecular film 6 incorporating an immobilized enzyme with catalytic properties, and a polyalkylsiloxane film 7, are sequentially formed on the electrode 2.
