<p>A carbon-containing carbon layer (3) is deposited on the surface of an electrically conductive substrate to form an electrically conductive substrate, and the surface of this carbon layer is covered with ion-sensitive films (4), (5) which generate a potential corresponding to a predetermined ion concentration. The resulting ion sensor can be shaped freely, particularly, can be made very small, and can measure an ion concentration in the blood vessel or a capillary.</p> |
