BIOSENSOR AND ELECTRODE SET USED THEREFOR AND METHOD FOR FORMING BIOSENSOR

摘要

PROBLEM TO BE SOLVED: To provide a biosensor which achieves an accurate analysis by forming a reagent distribution with a thickness enough to allow almost even chemical reaction. SOLUTION: The biosensor comprises a plate element having a specified reaction region and a recessed part disposed adjoining on the reaction region. It also has a reagent arranged in the reaction region. Preferably, the recessed part circumscribes at least a part of the reaction region.
