BIOSENSOR

摘要

A biosensor includes a cavity (8), through which liquid reagent is supplied by capillary action to an electrode part consisting of a measuring electrode (2) and an opposite electrode (3) on an insulating substrate and to a reagent layer (5) on the electrode part. The biosensor has a projection (10) on its side where an entrance (9) to the cavity is formed. The biosensor defines where to supply liquid sample and improves manipulability.
