BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biosensor, in particular an electrically insulating substrate, an electrode portion for detecting an electrical signal generated from a sample formed on the substrate and introduced from the outside, and formed on the electrode portion and electrically A biosensor comprising an enzyme reaction layer comprising a substance causing a chemical reaction, a spacer having an inlet for introducing the sample into the enzyme reaction layer, and a lid disposed on the spacer, wherein the flow of the sample An inner wall positioned downstream of the electrode portion along a direction and formed higher than the electrode portion; And an air outlet positioned downstream of the inner wall along the flow direction of the sample, for discharging air in the sample inlet space defined by the inlet, the substrate, and the lid. will be. |
