ABSTRACT:
A diamond electrode having a sufficiently low resistance is disclosed which is realized by increasing the amount of boron added thereto. A method for producing a high-performance, high-durability electrode is also disclosed by which adhesiveness between a diamond coating and a substrate and separation resistance during electrolysis are sufficiently increased. An electrode composed of a substrate and a diamond layer coating the substrate is characterized in that the electrode is composed of a base coated with diamond and the diamond contains boron in such an amount that the boron concentration is not less than 10,000 ppm but not more than 100,000 ppm. The base is preferably made of an insulating material.
