A microorganism-immobilized membrane or an enzyme-immobilized membrane, an electrode section that converts biochemical information from the membrane into an electrical signal, and an electrode in contact with one side of the membrane, and the membrane and a flow cell section forming a flow path for the sample and buffer solution on the other surface, the flow cell section having a flange at the lower end in which an opening for exposing the tip of the electrode section is formed, and at least one of the electrode sections. A cylindrical flow cell casing that accommodates and fixes the tip, a flow cell head that is held between the lower surface of the flange and adheres the membrane to the opening and forms the flow path, and that engages with the flange of the flow cell casing and A biosensor comprising a flow cell cap that is screwed into a thread groove on the outer periphery of the flow cell head to fix the flow cell head to the flow cell casing. 2. The biosensor according to claim 1, wherein the dimensions of the member are determined such that the lower surface of the flange and the lower surface of the tip of the electrode portion form substantially the same surface. 3. The biosensor according to claim 1, wherein the cylindrical flow cell casing accommodates the entire electrode section and is fixed via a presser disposed at the upper end of the electrode section.
