<P>PROBLEM TO BE SOLVED: To provide an electrode for electrochemical test/analysis having high corrosion resistance, durability, attrition resistance, and chemical resistance, having a wide potential window, and having satisfactory workability, as compared with a multipurpose electrode, and having an electron transfer velocity kept constant between lots, and also provide a device for electrochemical test/analysis using the same. <P>SOLUTION: This electrode for electrochemical test/analysis is formed by using a compound having a crystal structure made up of atoms of at least two elements equal to each other in mixing ratio. This makes it possible to obtain a potential window having nearly equal wideness to a before-proposed conductive diamond electrode. Above all, a compound, etc., comprising silicon and carbon, have high corrosion resistance, durability, attrition resistance, and chemical resistance, as compared with a conventional multipurpose electrode material, have low hardness as compared with conductive diamond to facilitate working/molding, and provide a monocrystal structure. Since it is also possible to keep constant the electron transfer velocity between lots, an electrode and a device for electrochemical test/analysis can be realized having a stabilized response characteristic to a redox reaction. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
