PROBLEM TO BE SOLVED: To enable efficient production of a wax fine dispersion free of impurities such as a shattered powder with the use of simple and undersize facilities in the method for producing the wax fine dispersion. SOLUTION: The method for producing a wax fine dispersion comprises supplying a wax-dissolving solution to a plurality of microflow paths whose width and height or inner diameter has a section of 1-1,000μm at a specified process flow rate and successively varying the temperature of the solution from the inlet of the plurality of the microflow paths to the outlet thereof along the flow direction as shown by curve 100 or 101 at a first stage of the temperature higher than the upper limit T<SB>1</SB>of the wax depositing temperature range, a second stage of the temperature between T<SB>1</SB>and T<SB>2</SB>within the wax depositing temperature range, and a third stage of the temperature lower than the lower limit T<SB>2</SB>of the wax depositing temperature range, and simply reducing the temperature along the flow direction at least down to the second stage.
