Abstract

An oxygen electrode comprising a plastic sheet, two or three electrode patterns formed on the plastic sheet, a paraffin layer formed on the peripheral portion of the plastic sheet for delineating a sensitive area, a carrier sheet impregnated with an electrolyte and placed on the central portion or the sensitive area of the plastic sheet, and a gas permeable membrane covering the carrier sheet and the paraffin layer. A biosensor may be also provided by further providing a microorganism or enzyme-immobilized layer on the gas permeable membrane of the above oxygen electrode.
