BIOSENSOR, MEASURING DEVICE FOR BIOSENSOR AND QUANTITATIVE DETERMINATION METHOD OF SUBSTRATE

摘要

PROBLEM TO BE SOLVED: To provide a quantitative determination method for reducing a measurement error generated by a biosensor for quantitatively determining substrate included in a sample liquid. SOLUTION: This measuring device has a support part for supporting detachably this biosensor constituted by forming at least a pair of electrode on an insulating substrate, a plurality of connection terminals to be connected electrically to each electrode, and a driving power source for applying a voltage to each electrode through the connection terminals. The biosensor has an electrode structure wherein, when inserted into the measuring device, either of the electrodes of the biosensor is connected to a first connection terminal and a second connection terminal provided on the measuring device only when the biosensor is inserted into the support part of the measuring device in a prescribed direction, and conduction is established between the first connection terminal and the second connection terminal by applying a voltage by the driving power source.
