Abstract
The present invention provides a biosensor which is arranged to generate an electric signal corresponding to an object to be measured. The biosensor is provided with a foundation electrode which is comprised of a working electrode, a reference electrode and a counter electrode, and on the surface of which is placed an enzyme film fixed with physiologically active material, so that an electric signal corresponding to the object to be measured is generated in the foundation electrode on the basis of the result of the enzyme reaction.
