Abstract:
1. A biosensor measuring an analyte contained in a sample, comprising: an insulative lower substrate that has at least one electrode on which an enzyme reaction layer reacting with the analyte is formed; an upper substrate that faces the lower substrate and consists of a conductive plate made of a conductive material, the upper substrate having an air outlet; and an adhesive layer that has a sample feed with a predetermined height on the enzyme reaction layer and attaches the upper and lower substrate to each other, wherein the sample is introduced to the enzyme reaction layer due to capillary phenomenon, an end of the upper substrate acts as a reference electrode in which an electron-transfer mediator contained in the enzyme reaction layer is oxidized or reduced, and the other end acts as an electrical contact part that electrically contacts a measurement unit.
