A titanium electrode for water treatment electrolysis, according to the present invention, is for oxidizing or reducing an aqueous solution to be subjected to electrolysis by applying a positive or negative potential while immersed in the aqueous solution, and comprises: a base made of titanium or a titanium alloy; a titanium oxide layer formed by oxidizing at least a portion of the titanium on the surface of the base; and an active layer made of any transition metal and coating the titanium oxide layer. Une électrode en titane pour une électrolyse de traitement de l'eau, selon la présente invention, est destinée à oxyder ou à réduire une solution aqueuse destinée à subir une électrolyse par application d'un potentiel positif ou négatif tout en étant immergée dans la solution aqueuse, et elle comprend : une base constituée de titane ou d'un alliage de titane ; une couche d'oxyde de titane formée par oxydation d'au moins une partie du titane sur la surface de la base ; et une couche active constituée de n'importe quel métal de transition et recouvrant la couche d'oxyde de titane. 본 발명에 따른 수처리 전기분해용 티타늄 전극은, 전기분해의 대상이 되는 수용액 속에 침지된 상태에서 양전위 또는 음전위가 인가됨으로써 상기 수용액을 산화 또는 환원시키기 위한 것으로서, 티타늄 또는 티타늄 합금으로 이루어진 기저부; 상기 기저부의 표면에 티타늄 중 적어도 일부가 산화되어 형성된 산화티타늄층; 상기 산화티타늄층을 코팅하는, 임의의 전이금속으로 이루어진 활성층을 포함하도록 구성된다.
