前記フィルタが、スクリーンフィルタで構成され、前記フィルタの前記基板と対向する面が前記電極系と非接触であることを特徴とするバイオセンサ。An insulating substrate, an electrode system having a measuring electrode and a counter electrode provided on the substrate, a reaction layer containing at least an oxidoreductase and an electron mediator, the reaction layer in contact with the substrate, and an air hole at a terminal portion A sample liquid supply path, a lower part of the sample liquid droplet for introducing the sample liquid, and a space between the sample liquid supply path and the lower part of the sample liquid droplet that does not enter the sample liquid supply path and is perpendicular to the substrate A filter for filtering the sample liquid in a direction, the filtrate is sucked into the sample liquid supply path by capillary action , and is horizontal to the substrate from the opening of the sample liquid supply path toward the air hole. A biosensor that passes in a direction,
The biosensor according to claim 1, wherein the filter is a screen filter, and a surface of the filter that faces the substrate is not in contact with the electrode system.
