PROBLEM TO BE SOLVED : To provide a production method of reformed fuel free of aqueous component in fuel after reformed, preventing flash point from rising and calorific value from lowering, free from oil/water separation, being stable for a long period, handleable similarly with base oil, and excellent in both aspects of economic efficiency and environmental protection, by applying pretreatment on fuel oil and water, making a mixture of both fuse together without being emulsified so as to obtain stabilized reformed fuel. SOLUTION : A production method of reformed fuel, where fuel oil and water are integrated without being emulsified, comprises : a step of bringing fuel oil and water into contact with a ceramic catalyst comprising a fired product of an alkaline earth metal, rare earths and a special noble metal with a complex of transition metals as a center; a step of adding a reforming promoter comprising an ester of a 16-22C fatty acid or condensed oxyfatty acid containing 50 wt.% or more unsaturated fatty acid and ≥4C polybasic alcohol to the fuel oil obtained in the former step; and a stabilizing step of stirring and mixing the fuel oil and water obtained from those steps, further stabilizing the mixture by applying ultrasonic vibrations divided into a plurality of stages.
