Abstract: A biosensor apparatus includes a substrate plate, a plurality of metal conductive layers, a plurality of working electrodes, a counter electrode and an insulating layer. Each metal conductive layer is disposed on the substrate plate and has a first upper surface. The working electrodes and the counter electrode are disposed on the corresponding metal conductive layers. The insulating layer covers the metal conductive layers and surrounds the working electrodes and the counter electrode, wherein the working electrodes and the counter electrode protrude beyond a second upper surface of the insulating layer, a first top surface of each working electrode is higher than the first upper surface of the metal conductive layer, and a second top surface of the counter electrode is higher than the first top surface of each working electrode. The above-mentioned biosensor apparatus can increase the sensing sensitivity.
