The present invention provides a diamond electrode that, in waste water treatment or production of functional water by using electrolysis, does not cause contamination of a solution or release of toxic substances, achieves enhancement of the energy efficiency, has excellent durability, and can endure prolonged use without damage The present invention further provides a treatment device where the above electrode is used, and a method for manufacturing the above electrode In a diamond electrode (Ia) according to the present invention, the electrode (Ia) includes a conductive diamond film (3) covering one surface of a substrate (2) Assuming that the thickness of the substrate (2) is T(µm) and the thickness of the conductive diamond film (3) is t1 (pµm), the ratio between them is 0 0010 <= t1/T <= 0 022 and 10 <= t1 <= 70
Lors du traitement des eaux usées ou de la production d'eau fonctionnelle par électrolyse, l'efficacité énergétique est encore améliorée sans contamination de la solution ni déversement d'une substance toxique. De plus, une électrode en diamant d'une durabilité excellente et d'un usage sans altération prolongé, un dispositif de traitement employant l'électrode et un procédé de production d'une telle électrode sont décrits. Une électrode en diamant (1a) comporte un film en diamant conducteur (3) couvrant une face d'un substrat (2) et, si l'épaisseur du substrat (2) est T (µm) et l'épaisseur du film en diamant conducteur (3) est t1 (µm), leur rapport satisfait à la relation suivante : 0,0010 = t1/T = 0,022 et 10 = t1 = 70.
