Abstract: PURPOSE:To make a probe which is a detecting part compact by covering the surface of a conductive thin film in contact with detecting liquid with an insulating metal oxide layer. CONSTITUTION:The entire surface of a probe 10 in contact with detecting liquid is covered with sensitive films 11a and 11b comprising metal oxide. The films are supported with a substrate material 12. The film 11a is provided by uniformly evaporating an SnO2 film on the entire surface by a vacuum evaporating method so as to obtain a film thickness of 4,000Angstrom . The film 11b is provided as a thin Al2O3 film to a film thickness of 5,000Angstrom on the film 11a by a vacuum evaporating method. The substrate material 12 comprises a steeple shaped hard glass chip. A probe 10 can be inserted into a blood vessel of the cell tissue of an organism. In this constitution, the surface potential of the oxide is changed sharply and reversibly for front concentration. Owing to the thin film, the change in surface potential is transferred to a lower conductive material layer across the film. Therefore, the signal can be taken out readily. Owing to insulating property, the effect of oxidation-reduction potential due to oxidation-reduction impurities incorporated in the detecting liquid becomes least, and S/N is improved.
