Kiso Electric Iron & Steel Manufacture, which inherited water right and hydro-electric power stations of the Kiso River possessed by Nagoya Electric Light Company, was founded in the middle of the economic boom of the First World War, whose business purpose was manufacture of iron & steel using electric power and the wholesale of electric power. This company was the predecessor of today's Daido Steel Company and at the same time the predecessor of Daido Electric Power Company, which was one of the so-called “five great electric power company” in the 1930's and developed to today's Kansai Electric Power Company. I analyse the business, unifying manufacture of iron & steel using electric power and the wholesale of electric power, which has been treated as a separate business so far, then show the reason of foundation of Kiso Electric Iron & Steel Manufacture, which secured water right of the Kiso, and study why water right of the Kiso was separated from Nagoya Electric Light Company. I also demonstrate the transition of iron manufacture plant based upon the newly found material. Kiso Electric Iron & Steel Manufacture came to a dead-lock by the end of economic boom of the First World War, besides technical trouble and turned the wholesale of electric power as main business, and iron & steel manufacture as its side job, and finally Daido Electric Power Company being established. Through these analysis, I want to show the meaning of following issue at the electric power industry; ① the formation of nation-wide wholesale industry of electric power, ② the transformation of electric supply system in the Chubu Area, and ③ the development of management by Momosuke Fukuzawa, so-called “king of electric power”.
