The method for producing a superheavy oil emulsion fuel includes the steps of (a) adding to a superheavy oil 0.1 to 0.6 parts by weight of a nonionic surfactant having an HLB (hydrophilic-lipophilic balance) of 13 to 19, based on 100 parts by weight of the superheavy oil, and water, to prepare a homogeneous liquid mixture; and (b) mechanically mixing the homogeneous liquid mixture with a high shearing stress, to produce a superheavy oil emulsion fuel having a particle size distribution. In this method, a 10 percent-cumulative particle size is from 1.5 to 8 'mu'm, a 50 percent-cumulative particle size is from 11 to 30 'mu'm, and a 90 percent-cumulative particle size is from 25 to 150 'mu'm, and coarse particles having particle sizes of 150 'mu'm or more occupy 3 percent by weight or less in the entire emulsion fuel, and the concentration of the superheavy oil is from 76.5 to 82.0 percent by weight.
