Disclosed is an emulsion-type water-mixed fuel which is free from separating between an oil and a water, thereby being excellent in stability, has a high combustion efficiency, and an extremely high energy-saving effect. An emulsion fuel, in which an average diameter of the water or the combustible oil is 1,000 nm or less (more preferably, average diameter is 200 to 700 nm), is formed by finely-dividing and mixing the water and the combustible oil by a finely-dividing and mixing means, while adding 10.0 to 150.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil (more preferably, 25.0 to 120.0 parts by volume of the water with respect to 100 parts by volume of the combustible oil). Further, the water to be used preferably has a reduction potential of −100 my or lower, more preferably −300 my or lower.
