Abstract: A biosensor strip includes a strip body, a working electrode and a chemical reagent layer, wherein the strip body has a conductive portion and a reaction channel. The partial wall that forms the reaction channel is a partial or an entire surface layer of the conductive portion. The reaction channel has an opening that receives the sample fluid and an electrode hole. The working electrode is embedded in the electrode hole.
