Biosensor
First Claim
1. A biosensor comprising:
- an electrode system including a working electrode and a counter electrode, for forming an electrochemical measurement system by coming in contact with a supplied sample solution;
an electrically insulating supporting member for supporting said electrode system;
a first reagent layer formed on said working electrode; and
a second reagent layer formed on said counter electrode, wherein said first reagent layer does not contain an enzyme, but it contains at least an electron mediator, and said second reagent layer does not contain an electron mediator, but it contains at least an enzyme.
