Abstract
A biosensor of the present invention is provided with an insulating base plate, an electrode system mainly consisting of a working electrode and a counter electrode formed on the insulating base plate, and a reaction layer on the electrode system. The counter electrode is partially a circular arc. A manufacturing method of the biosensor of the present invention is comprised of a step to form a base by arranging leads, an electrode system, and an insulating layer on an insulating base plate, and a step to form a reaction layer mainly composed of an enzyme on the electrode system. Since the counter electrode is partially in the shape of a circular arc, the reaction layer is easily formed and prevented from delaminating, whereby the measuring accuracy, preservative properties and reliability of the biosensor are improved. The present invention enables highly efficient biosensors to be mass produced at low cost.
