Abstract

PURPOSE: To perform measurement characterized by high sensitivity and excellent response by using at least two working electrodes where an electrode is arranged at the bottom part, the intermediate part or the upper part of each of many minute holes.
CONSTITUTION: Many circular minute holes 5 reaching a lower electrode 2 at the lowermost layer through an insulating film 3 from the surface are provided in a surface electrode 4. The surface electrode is used as an upper working electrode. The lower electrode 2 is insulated with the walls of the minute holes in the film 3 and provided at the bottom parts of the hole 5 so as to face the electrode 4. The lower electrode 2 is used as a lower working electrode. Thus, an electrode cell for minute use is constituted. These electrodes are formed of metal, half-metal or semiconductors. In this constitution, high sensitivity, high response speed and a large current are obtained. This cell has an excellent effect in high sensitivity analysis of low concentration samples.
