PROBLEM TO BE SOLVED: To provide a manufacturing method of a mold release agent capable of stably dispersing a wax in a solvent without heating the wax. SOLUTION: Almost all of a solid wax is ground into wax particles with a particle size of 5μm or below by stirring the solid wax and the solvent in a wet grinding and dispersing machine to obtain a dispersion wherein the wax particles are dispersed in the solvent. Accordingly, the wax can be dispersed in the solvent without being heated and melted by a conventional method, the labor for temperature control can be eliminated and the compounded mold release agent difficult to manufacture heretofore can be manufactured by dispersing a low boiling point solvent and a high melting point wax in a low boiling point solvent.
