A biosensor comprises a space part for sucking and housing a sample formed of two upper and lower plates, the two plates being stuck together by an adhesive layer, the space part for sucking and housing the sample being constituted so as to be partially opened in the peripheral part and partially closed by the adhesive layer, and has a working electrode having at least glucose oxidase immobilized thereon and a counter electrode on the same plane of the plate.

Biosensor

Enzyme electrode structure

A protein biosensor, which comprises an insulating substrate, a working electrode, a counter-electrode and a reference electrode, each electrodes provided on the insulating substrate, the working electrode comprising a first lead electrode and a thin protein-sensitive metallic film provided on the first lead electrode and the reference electrode comprising a second lead electrode and a silver/silver chloride electrode provided on the second lead electrode is simple in the structure and can be made smaller in the size, enabling easy manufacturing and operation, where measurement of a protein concentration is carried out with a carrier containing KCl or NaCl as dissolved therein.
